In 1998, the Suoja Ecological Museum in Liupanshui, Guizhou was completed. For more than 20 years, this ecological museum, which is composed of 12 local villages such as Happy Village, has broken through the limitations of collections and buildings, protected local natural styles, customs, production methods, etc., and explored a new path for the protection and development of traditional villages. A low wooden house is flanked by kitchens and bedrooms. The hall in the middle is the most spacious. A loom is placed in the middle, plus a bamboo basket and several plastic stools. Every day after dinner, Xiong Shaozhen, a villager in Xingli Village, Suoja Miao, Yi and Hui Township, Liuzhi Special Zone, Liupanshui City, Guizhou Province, weaves cloth here. At the age of 77, she specially prepares a pair of reading glasses for herself. She stepped on the pedal and held the shuttle in her hand. After a while, the fine twine was woven into cloth. "The loom sent by the government is still used, and it has not been overhauled for more than 10 years." Xiong Shaozhen said, "Before, the looms were all made at home, with three years of minor repairs and five years of major repairs." Now, in addition to their own insistence on weaving, the elderly also taught their daughter-in-law... Many villages formed an ecological museum to protect the local natural features, customs, production methods, etc. Why did the government send looms? It starts with the happy village becoming an ecological museum. In order to protect and continue the original ecological characteristics of the region, the Suoja Ecological Museum was built in 1998 with the approval of the Guizhou Provincial Government. The museum consists of 12 villages including Happy Village. "Different from the traditional museum, this is a museum without walls, which displays not only the collections." Luo Gang was assigned to participate in the preparation of the museum when he graduated from university in 1997. In 2013, he took over the work of curator. In his view, the clothing, language, music and even the way of production of the local people are all "living exhibits" worth preserving. "There are 25 ecological museums like Suoca in the whole province, covering 8 cities and prefectures." Yang Zhengquan, director of the Museum Department of Guizhou Provincial Bureau of Cultural Relics, said that the original intention of building such museums was to guide villagers to protect local natural features, customs, production methods, etc. spontaneously. Compared with traditional museums, ecological museums break through the limitations of collections and buildings, and benefit the local with original ecological culture according to the principle of sustainable development. In order to sort out and record various cultural forms, it is normal for Luo Gang to visit villages. In 2014, Happy Village was included in the third batch of Chinese traditional villages. At that time, Luo Gang caught a change in local production and life - there were fewer and fewer looms and spinning machines in the village. "Our traditional clothes are basically handmade. How can we do without our belongings?" After some research, Luo Gang found out the reason, "First, it is becoming more and more convenient for young people to go out to work; second, most of the looms are made by villagers themselves, which is not refined and easy to break." "In addition to collecting representative objects and preserving relevant information, museums should also focus on daily life to awaken people's attention to local culture." Luo Gang said. In 2014, he applied for funds from relevant departments, and then invited craftsmen who were good at making machines to the stockaded village to measure traditional looms and spinning machines. Within a few months, 50 looms and 50 spinning machines were successfully manufactured
