Inscribed in 2016 (11.COM) on the Representative List of the Intangible Cultural Heritage of Humanity Jeju Island, off the southern coast of mainland Korea, is a volcanic island with a population of about 600,000 people. Some landforms of the island were inscribed on the List of World Heritage in 2007. An average Jeju haenyeo holds her breath for one minute while diving ten- meter underwater to gather marine products. When a haenyeo exhales after each dive, she makes a unique sound called "sumbi-sori." A haenyeo works for six to seven hours a day in summer and four to five hours in winter. She dives about ninety days a year. The income generated from diving work significantly contributes to Jeju households. A Jeju haenyeo has her own mental map of the sea, including the location of reefs and the habitat for shellfish. She also has a command of local knowledge on the winds and tides. The maps and knowledge are acquired through repeated diving experience by each haenyeo. Most Jeju haenyeo rely upon upper-skilled haenyeo’s (sanggun) weather forecast for diving rather than listening to the official forecasts. Jeju haenyeo communities practice a shamanistic ritual for the goddess of the sea (jamsugut). The ritual includes prayers for safety at sea and an abundant catch. The ritual has a part for the haenyeo to sing a song called “Seoujet-Sori.” “Haenyeo Norae” (Haenyeo Song), which used to be sung while rowing their boat out to the sea for diving, has been an important part of Jeju haenyeo culture.

The construction of traditional Chinese timber-framed structures uses wood as the most important building material, with the structural carpentry as its foundation while containing other major divisions of work including the decorative carpentry, tile roofing, stone work, decorative painting, etc. The major wooden components, which consist of column, beam, purlin, lintel and bracket set, form the load-bearing frame for the whole structure. Two main types of framwork were developed as early as the 2nd century BCE. (Han dynasty), one is post-and-lintel, the other column-and-tie-beam. The wooden components are connected by tenon joints, which adds to the flexibility of the structure and improves its earthquake-resistent quality. Since the wooden components can be manufactured beforehand and installed on the spot, it can also significantly shorten the construction period.
