Sericulture and Silk Craftsmanship refers to the craftsmanship applied in traditional sericulture, silk dyeing and weaving process, which has been handed down from generation to generation, and relevant folk-customs derived thereby. China’s sericulture and silk craftsmanship boasts a history of 5000 years. The silk fragments, preliminary loom and potteries decorated with silkworm patterns excavated from sites dating 4000 years ago in the Taihu Lake area; demonstrate the time-honoured history of the sericulture and silk production in the region. Alongside the historical process, traditional manufacturing craftsmanship develops, and the main elements include: Mulberry planting: including cultivation of mulberry seedling, mulberry trimming, and various methods of engraftment; Silkworm production: including the selection, hybridization, and breeding of silkworm eggs, incubation, instruments for silkworm rearing, control of the temperature and humidity, and frame mounting methods; Silk reeling: including sorting and stripping of cocoons, ways for preserving the cocoons such as drying and salting, temperature control and process for boiling the cocoons, facilities and techniques for silk reeling, etc; Silk floss making: including techniques of water rinsing and tearing; Weaving tools: including various looms such as treadle looms, multi-shaft and multi-treadle patterning looms, lesser draw looms, greater draw looms, etc, and arrangement of heddle drafts and programming of patterns on draw looms; Design and weaving of fabrics: including the design and weaving of various structures and patterns, such as the Shuanglin silk damask which is calendared by stamp rocks, the Hang gauze with warps crossed, the Shu silk with warp-faced patterns, the Song-style silk in lampas weave, and Kesi woven in tapestry structures.

The Lum Medicinal Bathing of Sowa Rigpa (Tibetan Medicine) has been developed by the Tibetan people within a life view based on Jungwa-nga (five elements) – i.e., Sa (earth), Chu (water), Me (fire), Lung (wind) and Namkha (space) – and a view about health and illness based on Nyepa-sum (three dynamics) – i.e., Lung, Tripa and Pekan. In Tibetan, “Lum” indicates the traditional knowledge and practices of bathing in natural hot springs, herbal water or steam to adjust the balance of mind and body, to ensure health and treat illnesses. Influenced by the Bon religion and Tibetan Buddhism, Lum embodies folk experiences in illness prevention and treatment, and reflects the transmission and development of traditional knowledge represented by the treatise Gyud zhi (the Four Tantras) in present-day health practice. Lum is practiced under the guidance of a Manpa (traditional physician) in two ways. One is bathing in Five Types of Hot Springs containing different minerals. The other, bathing with Five Medicinal Nectars, includes three methods: immersion, steam-bathing and applications with sachets. In this process, Manpa, in collaboration with Lum Jorkhan (pharmacist) and Manyok (Lum assistant), conducts symptom differentiation based on observation, questions and pulse palpation. Then preparation of medicines includes herb compound, boiling, fermentation and addition of extra herbs. The element has been transmitted over generations through daily life, religious rituals, folkloric activities and medical practices on account of its safety and accessibility. While providing Tibetans with a sense of identity and continuity, the element reflects cultural diversity and human creativity.

Thagzo or the art of weaving is one of the oldest and widely used skills that have been practised for ages. The all-encompassing use of textiles represents prestige, artistic skills, discipline, determination, familial sentiments, tangible form of asset, and expressions of devotion towards the dharma. Bhutanese textiles are the product of knowledge and skills developed and nurtured over centuries of experiences and family traditions. Our textiles are valued and renowned for their richness of colour, sophistication and variation of patterns, including the intricate fibre preparation, dyeing, weaving, and embroidery techniques. This rich and complex art of weaving is an inseparable part of our culture and history. Today, the wide availability of imported fibres and dyes are transforming the palette, textures, and surface qualities of the clothes produced. There are more than eleven types of yarns and dyes including the five main colours (white, yellow, red, green and blue) and six subsidiary colours (orange, dark green, light yellowish green, pink, light white, blue and black). These different colours are woven in accordance with different designs and patterns. Women from central and eastern regions of Bhutan are famous for their weaving skills and each region produces their own specialty. a. Weaving with Designs and Patterns: Every textile product has a name that expresses its particular combination of colour, design, pattern and fibre. Weaving pattern is either stripes - vertical for men, and horizontal for women in cotton, silk or wool. Required extra designs are made by adding warp threads. Patterns like the vajra (thunderbolt), the swastika, the tree or the wheel, each has symbolic meanings. Although the symbols used in Bhutanese textiles are primarily of geometric nature, they also have deep religious meanings. Some common geometric symbols include the dorje (Vajra), the drame (nets), the phenphenma (butterflies), the phub (Kiliya), the yudrung (Swastika), and the shinglo (leaves). The drame or the eternal knot is a classic Buddhist symbol. The phenphenma is a symbol of butterfly and the eight-pointed star, while the dorje or the thunderbolt represents the indestructible powers of Buddhism. The phub or the rainbow is a triangle pattern in successive rainbow colours. When dorje symbol is incorporated within the phub symbol, the pattern becomes dorje\u0002phub. The shinglo symbol is used mostly on the royal and noble family dresses since this symbol is the most difficult to weave. The shinglo symbol represents the “tree of life”. The therpochay ( Jana chagri) or the China Wall pattern is usually seen next to the phub design on kiras. The therpochay symbol is believed to have been derived from the designs on Chinese brocade. The yudrung portrays the crossroads where the four directions meet. A yudrung represents the balancing forces of the universe, when rotating. The yudrung is an ancient pattern and its epicentre is considered a spiritual place. Yudrung is depicted on the royal thrikheb as the centre most design. Bhutanese weavers usually weave two types of textiles; the plain woven meaning kar chang, and the pattern woven textile called metochem. These are described below. a.1. Karchang: The plain woven textiles include pangtse, mathra, sethra, adang mathra, shardang thara, and pe sar. Plain woven clothes are worn at home or work since they are cheaper than the pattern-woven clothes. Mathra (red pattern) is a varicolored plaid woven on a maroon or red field, sometimes woven with stripes (khaja) at the edges. Sethra (gold pattern) is a plaid weave usually with yellow or orange field as the dominant colour. Sethra has two popular colour combinations; red with black or blue plaid on a white field; and yellow, white and black on an orange field. Sethra dokhana consists of black colour in it while buechapgi sethra does not contain black. Thara has horizontal stripes with white as a dominant field. Shardang thara has multicoloured stripes while Samkhongma have narrow red-and-blue stripes, and Mondre which has a similar pattern to Samkhongma is worn mainly by older people in rural areas. Kamtham Jadrima is a striped textile with colours of the rainbow. Kamtham thara consists of simple warp stripes or plaids, which are gifted to a religious person. Pesar (new design) is a modern innovation with small patterns in striped plain cloth. Yu tham or the country cloth which is made of wild silk or cotton is very popular in the rural areas. Kawley is a completely black fabric of wool, which is believed to have healing properties. a.2. Meto Chem: Aikapur and Ku shu thara are the two specific kinds of pattern-woven textiles. Pattern-woven clothes are considered special, and are valued and saved for special occasions like festivals, marriages and for New Year celebrations. Bhutanese weavers weave many different types of clothes with intricate designs such as leaves, birds, trees and other animal patterns. These are briefly explained below. Aikapur: Aikapur is a textile woven of cotton or silk, and appears to be embroidered. Aikapur has double faced pattern bands called hor which alternate with rows of plain weave; with always an odd number of legs ‘kangpa’ or cross hatches. A textile is referred to as a b-sampa (with three legs; b-napa (with five legs); b-zumpa (with seven legs); b-gupa (with nine legs); b-songhthurpa (with eleven legs); and b-songsampa (with thirteen legs). Aikapur is differentiated by the colour of the background thread, and the supplementary thread used. The common colours used in aikapur are: dromchu chema, literally meaning ‘little boxes’, with red, green, yellow, and white pattern bands. Mentse mathra is a material with a yellow base, and with red and green stripes. Montha has a blue or black background with red pattern bands between colourful stripes. Lungserma has green and red pattern bands on a yellow background. Shinglo or ‘tree of life’ patterns made on the fabric are used to assess the quality of an aikapur. The delicate branches and leaves of these trees are inspected when judging the quality of a textile. Kushu Thara: Kushu thara used to be considered aristocratic and the most prestigious dress for women. Ku shu thara is woven from vegetable dyed cotton and raw silk (bura) or entirely from silk. Ku shu thara has spectacular brocade design which take up to a year to weave. Ku shu thara is always embellished on a white base, and a similar kira with a blue or black background is called ngosham .Sapma, the continuous weft patterns, and tingma, the alternative weft patterns are used as base pattern for kushuthara, ngosham or shinglochem. Shinglochem can be either a gho or a kira, woven with alternate rows of warp pattern bands. b. Weaving Materials: Bhutanese produce fibres such as raw cotton, wool, nettle fibre, yak hair and bura (raw silk). The most expensive and the most valued fibre in Bhutan is raw silk. The Bhutanese do not kill the silk worms that remain inside after spinning its cocoon, but are left until they escape, which breaks the thread before it is unrolled. That is why, Bhutanese raw silk feels and looks relatively coarse compared to Indian and Chinese silk. Several types of yarn like seshu (cultivated from mulberry silk moth Bombayx mori), bura (produced by wild non-mulberry silk moth), namdru kuep (parachute silk), and varieties of silk imported from India are notable. b.1. Nettle: Nettle or stinging nettle, though now rarely used, is said to have been the original and chief fibre used by weavers in ancient Bhutan. Nettle fibre is coarse but strong and durable. That is why people in villages used it to weave sacks, bags, kurel, pagi, pakhi, bundi and tabden. Owing to its strength it is also used as bow string. Nettle is herbaceous flowering plant that grows in temperate and sub-tropical zone. The plant grows up to 2 meters in height with spiny stems and leaves and bears white to yellowish flowers. Nettle bark contains baste fibre which is strong, smooth and light. In Bhutan, nettle fibres are harvested in the months of October and November. After peeling the stems, the fibres are dried, and then cooked with ash for about 6 hours. The fibres are then washed with cold water, and beaten in order to remove the outer cover. After removing the outer cover, the fibres are dried and dyed with natural dyes. The nettle plants are shredded, and twisted into thin fibres using a drop spindle. Nettle fibres are used to weave bundi or carry bag. Bundi is usually woven with brocaded yudrung motif at the centre of the middle panel, on a white colour base. The bundi or carry bag consists of three lengths of cloth sewn together to form a square panel. Ropes on the diagonal sides of this piece are tied together to carry possessions and bedding. b.2. Wool: Yarns from yak, sheep and goat wool are spun using phang (drop spindle) and moved to a chaphang (spinning wheel). The herders of the high valleys of Merak and Sakteng weave shingka (tunic-style dresses), women’s jackets and belts. They also make hats, ropes, tents, and bags out of yak hair, and floor mats and blankets from sheep wool. The Layap women’s dress includes a black woollen jacket, a long woollen skirt, adorned with lot of jewels, which often include teaspoons. Women also wear conical bamboo hats with a bamboo spike at the top, held by beaded bands. Shingka, an ancient tunic-style textile that was woven with either a ngoshingkha (blue) or a laushingkha (red) wool base, was worn by a high lama during religious ceremonies. Char khab, woven from wool (of yak or sheep) either on a pedal loom or back strap loom is used for protection from snow, cold, and rain. It is water-resistant and an essential item for the herders in cold the region. Sephu charkhab (rain cloaks from Sephu) is a colourful textile with bands of green, blue, white and orange. Bumthang and Trongsa were known for a woollen fabric called yathra, which was used as a cover from rain and cold. In the late 1990s, farmers in Trongsa had stopped raising sheep which inevitably put an end to the practise of weaving yathra. Yathra is used as bed covers, blankets, rain cloaks, cushion covers, sofa set covers, and as jackets for both men and women. b.3. Cotton: Kershing (cotton) is used to separate the cotton seeds, and then fluff out to make it ready for spinning into yarn with the help of a wooden spindle or spinning wheel. Usually cotton woven with traditional designs on white background, chagsi pangkheb was put on laps to wipe hands before and after meals by persons of higher positions. In the early days, Bhutanese women used to put on an apron-like wear called dongkheb as a sign of respect while approaching the king or a high official. Phechung is a cotton woven carry bag woven but its usage is now limited to ceremonial receptions along with chagsi pangkheb. Thrikheb (throne cover) is a rare textile used as the King’s throne cover. It is also used for the lamas during religious ceremonies. Chephur gyaltshen (banner with frills), gyaltshen (pair of cylindrical hangings with valance), bumgho (bumpa covers), kheb and tenkheb (altar covers),phen (pair of triangular topped hangings) and chephur (a pair of cylindrical hangings) are some of the other cloth products that are used in altars and monasteries. Hingthub is a time-consuming but highly cherished textile woven for loved ones or for use by the weaver or their ‘lord’. The finer product demonstrates the dedication of the weaver. It is also used by the weaver’s family or to stitch outer attire for statues or as wall hangings. Today most of the yarns for weaving like raw silk, cotton and acrylic are imported while some of the yarn is spun and processed locally. The availability of cheap machine spun yarns from India has overtaken the local cotton cultivation. b.4. Types of Loom: There are three types of looms used by weavers in Bhutan. Traditionally pangthag was the most commonly used loom for weaving larger size garments. The smaller version of this loom called kethag is used for weaving narrow items like belts. In the 1970s, another type of loom called thri-thag (khri-thags) was adopted from India. This loom gained popularity in the growing urban centres. This later type is a horizontal loom with pedals. Each region has a speciality in terms of designs and types. Kurtoe is known for Ku shu thara, while marthra and serthra are mostly produced in Bumthang. Trashigang district is well known for weaving aikapur, while pangkheb and montha come from Kheng. b.5. Dyes: Bhutanese weavers consider the coordination of pleasing colours more important than the designs, patterns and techniques. Strong taboos are associated with the dyeing process and the weavers are very particular about colour shades. They believe that malevolent spirits, certain weather conditions, strangers or pregnant women can ruin the dye. Like the weaving techniques, the recipes for dyeing are closely guarded family secrets and the formula is usually passed down from mother to daughter. There are a number of dye-yielding plants. Weavers obtain dyes using simple methods from barks, flowers, fruits, leaves, and roots of plants, and minerals. Today, chemical or synthetic dyes called tsho-sar are easily available while the natural dye is called tsho nying. They are easily recognisable by their hue. Some of the natural dyes obtained from plants are described below. - Indigo: Shades of green, purple, blue and black are obtained from leaves of trees locally called yangshaba (Strobilanthus flaccidifolius) in Tshangla dialect. Indigo (lndigofera spp.) plants are cultivated in household gardens as a source of blue dye. Alum earths, sour fruits, and dug shing (Symplocos) leaves are used as a mordant in dyeing to fix the colouring matter. Indigo plant leaves are fermented for two weeks, and then passed through acidic ash water. - Lac: Jatsho (Lacifer lacca) is an organic dye that produces colours ranging from pink to deep red. Lac is boiled in water until it becomes sticky dough. The pulp is mixed with roasted wheat and allowed to ferment for 10 days. The selected yarn is then put into the boiling mixture until the colour gets absorbed. Churoo (Phyllanthusemblica) is used as a fixating element in dye. - Madder: Dried stems and leaves of madder called tsoe (Rubia cordifolia) are chopped into small pieces. This material is boiled together with the yarn to produce several colours ranging from pink to deep red. It is good for dyeing raw silk, cotton and wool. Madder can be preserved in dry place for years. The ripe berries of berberis, locally called kepatsang (Berberis aristata) are used as a source of red colour, while the barks of nut of the walnut tree can be used to obtain orange colour in woollen yarns. - Pangtse: Leaves from pangtse shing (Symplocos paniculata) are gathered from the forest, which can be used fresh or dried, to make yellow colour .Pangtse leaves are boiled in water along with woollen yarns. The yarn is then allowed to drip. Sometimes, yung ga (Curcuma longa) or turmeric is also used to obtain a bright yellow colour. Lemon, also called churoo (Emblica officinalis), variety of other berries, herbs, plants, and roots are used along with alum mordant to boost colours in the yarn. However, since dyed yarns from India are available at cheaper price, only a few Bhutanese weavers practise the tradition of natural dyeing processes these days.

"Salt" is an essential ingredient for many kinds of foods and helps keep the human body strong and healthy. Not only that, salt is also used in many other ways, in everyday life, in the food and cosmetics industry, and in spiritual ceremony. To this day, Cambodia does not have to worry about finding salt ores, as there are coastal provinces that can produce enough salt to supply the country's consumption. In the past, the people who live along the seaside traditionally made salt by extracting seawater and boiling it into salt, and that production was only for family use, not for sale. Then, in 1941-1942, a Cambodian named Poch deforested Ang Kol area (now in Phnom Leav commune, Kampong Trach district, Kampot province) to produce salt. At that time, he brought a Chinese man named Cheng from Bassac district (Kampuchea Krom) who knew how to make salt to help. Later, other businessmen came to do this business, so the salt production became more and more widespread until it reached the factory for processing salt. Some people in that area can grow rice and harvest salt because rice planting and salt production are done in different seasons. Rice is grown in rainy season and salt is produced in the dry season. The salt evaporation fields are generally inactive after the New Year. The way to cultivate salt fields is that they first need a fairly large amount of land near the sea, because they have to drain salt water into a large dam called“Srae Hal” or salt evaporation field. After that, they have fields that are built with dams next to each other, continuing inside the mainland. The salinity of the salt is calculated by measuring the salinity with a thermometer. The water in the dry field has a salinity of only "level 2". Then the water is left to "sleep" overnight in the dry field and then drained into the next field, where the salinity level rises to 5 degrees. "If the salinity level reaches "level 2" no plants can grow, not even sea fish can survive, and the bottom of the field is unusually hot. The water at this point is only around 4cm deep. The next day, it was drained to another field, when the salinity level reached "10". This was done until the end of the field, where the salinity level had risen to “level 25”, and a lump of salt appeared. The last field is called "cooked field," and the salt that is formed is called “Grow”. The work here is called “cultivating salt”. They have to hurry to "collect" and put it in storage every day, otherwise, the salt will freeze. When it is around 8cm high and the salt will harden like a rock. The hotter the day, the faster the water evaporates, and the faster the salt grows. The water is very hot, can reach 45 degrees. When collecting salt every day, sometimes it rains. If it rains a little or moderately, it does not cause any major problems, but if it rains too much, fresh water is drained through a canal. Drainage is not difficult because fresh water is lighter than salt water, so fresh water is on the surface. On the other hand, if fresh water is not drained, it will cause moss to grow suddenly. That is why the first thing to do is to clean the canals and clean all the fields so that there is no moss and then compress the soil. The salt depot must be built from plants such as wood or bamboo, etc. If metal is used, it will be rusty.
