Tamzhing Phag-chham is a solo mask dance with a mask made of a wild boar (Sus scrofa), which is very common on the Asian continent. The term "Phag-chham" sometimes has two different meanings; Phag-chham (tamzhing Phag-chham) and the other, the Phag-chham performed during the Raksha Mangchham (a theatrical mask dance of the Intermediate state). Tamzhing Phag-chham was originally composed by the Great Treasurer Terton Pama Lingpa (1450-1521) on the consecration of the temple Tamzhing Lhundrub Choeling on the 15th day of the Tiger Month (11th month) of the Wood Ox Year, which corresponds to the Gregorian year 1505, in Bumthang, one of the central districts of Bhutan. Later it was performed in other monasteries founded either by Terton himself or by his successors in most of the eastern and central parts of Bhutan. Phag-chham is among the most important and sacred mask dances in Tamzhing, and the festival "Tamzhing Phag-la Chod-pa" is also named after this dance, which is held every year from the 10th to the 12th of the eighth lunar month. It is performed by an amateur and can only be danced by the Chhamjug (the second leader of the mask dancers), who wears a wooden boar mask, exquisite brocade costumes with dangling skirts made of five eye-catching colored cloths, and holds two bundles of willow branches in both hands. The boar mask is considered one of the masterpieces of the founder himself, as are the dance steps themselves. Since the mask is considered sacred, it is received in a Chibdrel (traditional procession) when the dancer comes out of the Chhamkhang (preparation room). The origin of the mask dance lies in local tradition: Pema Lingpa was looking for a suitable place for his temple in the Choekhor valley when he saw a wild boar digging in the ground. He realized that this was a sign from the enlightened being Dorje Phagmo (deity Skt. Vajravarahi) to show him the suitable place. After the temple was built, he held a festival in honor of the patron deities during the inauguration as a symbol of gratitude. Since it is believed that the prophecy and the groundbreaking ceremony for the Tamzhing Temple was led by Dorje Phagmo, the festival is dedicated to her and is called Phagla-Chodpa. On the second day of the festival, Phag-chham leads the ground-breaking ceremony to sanctify the site before more mask dances are performed for the audience. Due to the unexpected loss of the Chham-yig (choreography manuscript) from the monastery many years ago, elders have regretfully found that the Phag-chham performed today no longer contains the complete steps and choreography. Elderly locals says that, at that time, there were more than 14 different types of steps, and due to faulty oral tradition, nearly 50% of the choreographies have been lost. The communities are concerned that without documentation, there is a risk of even more steps being lost and even new ones being added, as many of the artisans are either lay monks or farmers from the affiliated communities.

It is said that besides the naked dance performed during Jampa Lhakhang Drub, there are also naked dances performed during Nabji Drub in Trongsa and Sakteng Tercham, Trashigang and in Dagana. The naked dance is honorifically referred to as a “tercham” a term usually applied to dances revealed as treasure. Just as any sacred ter (treasure or precious object) is not exposed freely to the public so also our nakedness is never exposed publicly. So the dance performed naked and exposing the genitals is exceptional and hence considered tercham or the “revealed treasure dance”. According to the book Invoking Happiness, the dance has its origins during the construction of Jampa Lhakhang, when local spirits disrupted the process45. The story recounts that King Songtsen Gampo manifested himself in the form of several people dancing naked, which fascinated the troublesome spirits. As they remained preoccupied by the dancers, the temple construction was completed and consecrated. According to Chagkhar Lama Dorje, Dorje Lingpa introduced the dance at Nabji, Trongsa. One oral account maintains that when Dorje Lingpa was constructing Nabji Lhakhang, local spirits were disrupting the process every night. In order to distract the spirits, Dorje Lingpa used his miraculous power to summon naked people from the Treasure Cliff located opposite of Nabji Lhakhang. He made them dance, and antics kept the spirits spellbound enough so that Dorje Lingpa was able to complete the temple and consecrate it. Thus, according to this account, the tercham was first performed at Nabji under the supervision of Dorje Lingpa. When Dorje Lingpa later renovated Jampa Lhakhang, the dance was performed during the initial consecration ceremony and is said to have been enacted every year since. At Jampa Lhakhang Drub, tercham is performed each of the first three nights. The performers are chosen from the five villages of Drub Tsawa: Chagkhar, Jampa Lhakhang, Changwang, Nasphey and Nobgang. After the normal mask dance performances are concluded, a crowd gathers around midnight at the performance ground in the outer courtyard of the western side of Jampa Lhakhang. Shortly after midnight, a group of ten men emerge from the chamkhang (room for dance preparations) and dance to the rhythmic beating of traditional mask dance drums and cymbals. The men are all naked except for their faces, which are covered by a white cloth to conceal their identities. The last man, who is the dance master, wears shorts. The group dances around a bonfire located in the middle of the performance ground, sometimes acting outrageously towards the spectators. The dance lasts for an hour despite the cold, which drops to around one to two degrees Celsius. Photos or any type of recording is strictly prohibited, as is the use of torches. Policemen and village locals guard the integrity of the performance, and deal harshly with anyone who attempts to break the stringent rules. Chagkhar Lama Dorje describes the dance as most sacred and says that spectators should not look at the dancer’s genitals as just male organs. As the male genitals are never exposed publicly, it is one of the world’s precious ter. All sentient beings are brought into the world, in part, by this organ. Local elders explain that though the younger generation may find the dance funny, it was started by the great saint Dorje Lingpa, and therefore one should view events with devotion rather than as entertainment. In the recent past, the dance was banned by the Dzongkhag Administration, who deemed it vulgar and embarrassing. Once banned, there was abnormally heavy rainfall and hail, and the Drub could not be properly conducted. Local astrologers attributed downpours and bad weather to the tercham ban. The local people conducted kangsol rituals to repair the relationship with the protective deities and the Dzongkhag Administration lifted the ban the following year.

The Nàng Hai Festival, also known as the Moon Praying Festival, begins in January and lasts until mid-March with the symbolic meaning of mothers and fairies on earth going to heaven to welcome Mother Moon and fairies down to earth. The Ngan ethnic group believes that on the Moon there is Mother Moon and 12 fairies, her daughters, who always take care of and protect the crops of all people. They choose a mother to be Mother Moon, and the girls play the role of fairies, including two unmarried girls who play the two moon sisters. The characters all wear traditional costumes according to regulations. They set up a "moon tent" as a place for Mother Moon and the fairies to sit during the ceremony. Before the ceremony, the people playing the role of Mother Moon (Mụ Cốc) and the girls stand in front of the altar so that Mr. Tào can perform the transformation ceremony for the souls of Mother Moon and the fairies to enter. From then on, they must abstain according to regulations. The ceremony is held on a large field with the rituals of "worshiping the local land princess" at the communal temple to ask permission for the villagers to organize the Moon-praying festival the following night. According to tradition, the ritual of carrying offerings from Thanh An communal house to the outdoor altar is a very important part to invite the gods to witness. The procession consists of 8 young people carrying the palanquin, including 4 men and 4 women, led by the shaman and the dancers, followed by trays of offerings including a pig's head, 4 pig's feet, chicken, duck, wine, cakes, and five-color dyed sticky rice. The shaman worships the local land goddess and the gods, the artists perform the rituals of dancing around the altar when the Moon-welcoming festival opens. After completing the ritual of reporting to Mother Moon and the 12 fairies, the village elder performs the rituals of praying for blessings, good luck, favorable weather, good crops; inviting Mother Moon and the fairies to bring crops and blessings to the villagers. The ceremony lasts for twelve nights. Each night, a Mother is invited. After that, they held a ceremony to send the moon ladies back to heaven. As for the festival, the shaman blew the trumpet and opened the festival. Villagers and commune residents participated in traditional sports activities such as: men's and women's volleyball; blindfolded duck catching; and pond fishing. In addition, the festival featured performances of folk songs, then singing, coi singing, folk games, and traditional cuisine of the Ngan ethnic group such as bamboo-tube rice, wild vegetable dishes, pork fish sauce, field carp fish sauce, salted plums, five-color sticky rice, pickled bamboo shoots, black plums dipped in sesame salt. This is a unique folk festival imbued with spiritual colors, with a positive and highly educational nature in the Ngan community. With its unique cultural values, the Ngan ethnic group's Moon Praying Festival was recognized as a national intangible cultural heritage by the Ministry of Culture, Sports and Tourism in 2018.

Nub Tshona-patra literally means "The Great Lake in the West" and is beautifully situated between the ancient trade route of Haa and Tibet. From some sources, "Nub" may also be known as Nob, which means Norbu (precious treasures). Nub Tshona-patra is considered one of the most sacred and revered lakes in Bhutan. It is believed that the lake is so large that two types of vegetation grow on the lake. On the Tsho-gu (head of the lake) grow plants commonly known as Chukar meto (Rheum nobile), which grow only in mountainous regions such as Jomolhari, while on the Tsho-ju (tail of the lake) grow Dungshing plants (Abies densa), which grow in low regions such as the Haa Valley. Nub Tshona-patra is one of the holiest lakes in Bhutan and can be hiked from Haa on many different routes. The most common routes are from Kipri in Uesu gewog, from Karjena in Kartsho gewog via Changzur Nyela to Drakna Trashiding-kha Gonpa and also from Tokey in Bji gewog. Nub Tshona-patra can also be reached through Jula Pass, Talila Pass, from Miri Pun Suum and from Norbugang in Samar gewog. The river that flows through Dozam at the foot of Chana Dorje (Vajrapani bodhisattava) hill is fed by Lake Tshonapatra. This river feeds the Haa fishery at the foot of Chana Dorji hill. This river flows through Nakha Tashigang and Shubji in the Sangbay Gewog and joins the Amochu further downstream. The river from Baytsho also flows along this river. The sanctity of the lake brings about the fact that Terton (treasure revealer) Sherab Mebar (1267-1297?) came to Bhutan from Kham in Tibet in the 13th century at the age of thirteen, settled in Paro Pangbisa and established the Pangpa Ugyen Guru Temple as his seat. Even today, this two-story temple is considered very sacred. According to oral traditions, he was destined to recover treasures from a lake in western Bhutan. He was also destined to visit Bumthang and the Jawar Tsedrag Goenpa (temple). To find the treasures, Terton Sherab Mebar traveled to Haa. After finding the lake (now Nub Tshona-patra), he unveiled many treasures including gold, religious artifacts and religious instruments such as dung (trumpet), Nga (drum), Nge-tok (drumstick) and a pair of Rol-mo (cymbals), among others. Terton was prophesied to visit Nub Tshona-patra seven times. When Terton came across a huge lump of gold in Nub Tshona-patra, it turned into a giant frog as big as a hill and swallowed (and held) all the water of the lake in its mouth. He asked a carpenter to carve the gold nugget into a pillar to be used in Paro Dzong. The carpenter was instructed to take the splinters and fragments of the pillar as payment for his work. However, the carpenter tried to shear off too much of the column in order to receive his wages. The Terton feared that the column would be too short, and when he tried to talk to them about shearing too much out of concern, a drop of water fell out of his nose and spilled into the lake, drowning them all along with the gold. Some locals believe that those who cut off the gold pillar were his one hundred and five monk disciples from the village of Pangbisa, while others say that his team consisted of thirty-two strong men who were farmers and carpenters. The angry deity of the lake Tshodag/Tshomen (mermaid) sensed this and began to pursue the Terton. While he was running for his life, religious instruments such as cymbal, trumpet, drum, drumstick and a sickle fell from him, and lakes sprouted in the place where the treasures fell. Locals know these lakes as Drum Lake (Nga-tsho), Drum Lake (Dungtsho, in Jarey), Drumstick Lake (Ngetok-tsho), Cymbal Lake (Roel-tsho, in Rigona), and Sickle Lake (Zoutsho), which are now found in the Haa Shongana region (also known as Shokuna), including Nub Tshona-patra in Tshona Diga. Ngatsho and Ngetok tsho are located close to each other at Tsoo. Yak herders spend their summers in Tsoo. Locals believe that the Terton also spent time meditating (thukdam/tsham) in Yatokha, the area behind the hills of Ngatsho and Ngetok tsho, to see clear visions and find hidden treasures. Some sources say that the Terton also dropped other treasures such as religious artifacts and religious instruments made of gold, turquoise, silver, shells and a vase during his escape, which led to the formation of Ser-tsho, Yu-tsho, Ngyul-tsho, Dungkar-tsho and Bumpa-tsho (in Jarey Damshog). The terton Sherab Mebar turned into a bird and the angry deity into a falcon. When they reached Tergola (which means "gateway to hidden treasures," as it was believed that many treasures were hidden behind this mountain pass), the deity of the mountain (Tsan) negotiated peace between the Terton and the angry deity of the lake. Some consider this Tsan or Drak-tsen to be Ap Chungdu. Some sources also indicate that the negotiation actually took place in Lab-dza of Tshellu-tsho. It was agreed that both Terton and the deity would not enter their respective territories. Terton and the descendants of his followers would never set foot in Haa Shongana. Similarly, the lake deity agreed not to cross Tergola. Thus, all connections between the people of Haa Shongana and Paro Pangbisa were severed, even though these two places are considered to be close to each other. Even today, when the descendants of the Terton people in Pangbisa cross the Tergola Pass, it rains even when the weather is fine, and people die when they enter the Haa Shongana region. Animals also die when they cross the border, or if animals are traded between these two places, they do not survive. However, some of the locals believe that this border does not apply to livestock. To resolve the conflict between the two, the mountain deity erected five Do-tshams (boundary stones) between Gangche-la and Zou-tsho (Sickle Lake) to mark the border. It is believed that the boundary was initially marked with dried yak and sheep dung, which later turned into stones. The cairns are still preserved today. The Do-tshams are located in Ramzur, under the Uesu gewog. The stone mounds look as if they would collapse at any time. But if you actually touch them, it is not easy to dismantle them or break them into the ground. People say that stones and pebbles can be added to the piled up structures, but they should not be removed or disintegrated. When the Terton died, he left the only Rol-mo treasure (basin) and a Phurpai ku (three-sided ritual dagger statue) in the Pangpa Ugyen Guru Temple. The Phurpa ku can be seen in this temple to this day as one of the Nangten (sacred religious objects). It is said that after the death of Terton, his Kudung (sacred body) was taken from Pangbisa to Rinpung Dzong (fortress). However, the people of Pangbisa wanted to reclaim the Kudung, and when they tried to steal the Kudung through the U-tse (central tower) of Rinpung Dzong, the "head" detached from the Kudung, and the headless Kudung was left in Rinpung Dzong, which later burned in a fire tragedy. Today, the skull of Terton is revered as one of the most important sacred relics of the Pangpa Ugyen Guru Temple. In lieu of formal punishment, the people of Pangbisa had to cede the only treasure, the Rolmo, to the Rinpung Dzong. This cymbal can be visited today as one of the most important sacred relics of the Rinpung Dzong. The cymbal is shown to the public once a year, on the first day of Paro Tsechu, to give blessings, and it is also used to determine the timing of the mask dancers during Tsechu. The other cymbal that belongs to this treasure was newly made; therefore, this pair of cymbals sounds slightly different from the other normal pairs of cymbals. Some believe that the Nub Tshona-patra was originally located in the village of Sangbay Ama in the Sangbay gewog before it was settled in its present location. People say that a mermaid carried the lake in a dung-chung (slender container made of bamboo used to store salt) and planned to move the lake to another location because the lake's location was either dirty or it was time to move away from Sangbay Ama. On the way to the present location of the lake, the mermaid stopped for a night at a Norgi-jangsa (settlement of cattle herders). It is believed that the mermaid gave cattle to the Nublang cattle as a reward for the kindness shown to her by this local herdsman. Today, this particular breed of Tha-nor (low altitude cattle) exists only in the Sangbay gewog of Haa. Before the lake was built on the present site, the place was a Bjobi-lakha (nomadic settlement). The mermaid asked the shepherds to move their camp so that the lake could settle there. The mermaid found that even the next morning the shepherds had not moved away. So, the mermaid emptied the Dung-chung that contained the lake's water, drowning all the shepherds along with their camps. It is believed that some lucky people on a clear day can see the entire Nogi-jangsa, including dogs, yaks and people. Legend has it that once a woman from Tshaphel village was washing clothes on the lakeshore and polluted the lake. Nothing happened to her for five years. But in the sixth year, the lake "consumed" and she drowned along with her livestock and camp. To this day it is believed that at Nya-chhu, the source of Haa fishing, people come across pieces of clothing or Bjob's hat. It is believed that it is a bad sign to find such items. Locals also believe that whenever the waters of Lake Nyaku-na appear in Tshaphel, people either die or mysteriously disappear. It is believed that Dungkar Aekhil (a shell with a right head) appears to those who have good luck when visiting the lake. Lam Duetsi from Dumchog village in Uesu is said to have seen this shell while visiting the lake. Local people believe that a hundred cattle once drowned in the lake because the water of the lake appeared so calm that the cattle mistook the water of the lake for the ground. Later, about nine tethers that were used to tie the cattle were found at the water source that feeds the fishery in Haa.
