On June 7, 2008, Tansheepskin tanning technology was approved by the State Council of the People's Republic of China and listed in the second batch of national intangible cultural heritage list, item number_-111.

historical origin

The tanning technology of Jiaochengtan sheepskin originated in the mid-Ming Dynasty and lasted for more than 400 years. "China Industrial Chronicle" once described Jiaocheng fur industry: "Shanxi is famous for sheep herding, and the tannery industry developed with it. In the late Ming and early Qing dynasties, there were already tanneries in Datong and Jiaocheng. "Jiaocheng leather goods with beach skin as the most famous, exquisite manufacturing..." Jiaocheng fur industry reached its peak in Ming and Qing dynasties.

According to the records, there were still more than one hundred Pifangs in Jiaocheng in the late Qing Dynasty and the early Republic of China, with an annual total output value of more than 3.1 million silver dollars. At that time, there were more than 10,000 workers working in Pifang. Among these people, only 2,000 people lived permanently in Jiaocheng City, and more than 9,000 were migrant workers.

In 1933, the Ministry of Education of Nanjing National Government published a "Overview of the Latest China Situation" which introduced Jiaocheng as follows: "Turen are good at making cattle and sheep skins, Jiaochengtan sheep skins are well-known throughout the country."

After the outbreak of the War of Resistance Against Japan, the fur industry in Jiaocheng shrank rapidly. Traffic interruption led to the passivity of raw fur and the lack of access to products. In addition, the products plundered by the aggressors resulted in the bankruptcy of fur shops, leather stores and related financial and service industries. A large number of workers lost their jobs and went to Zhangjiakou and Taiyuan to make a living. After the founding of New China, Jiaocheng fur industry once recovered. First, "Heji" fur shop was opened and small batch production was carried out.

After the founding of New China, a "local state-owned Jiaocheng fur factory" was established. The tanning technology of Jiaochengtan sheepskin was inherited. It went bankrupt in the 1980s, and the tanning technology of Jiaochengtan sheepskin was in danger of being lost.
