Now Yu's entire family, including her three brothers and her husband, are involved in different parts of the jadeite industry. She travels frequently between Tengchong and Kachin for her business.

According to Yu, people's tastes and their understanding of jadeite has changed over time, which has also exerted great influence on the industry.

"A few years ago, products with relatively low prices were the best sellers, but now, the situation has changed, and high-end products have a better market," Yu says.

Besides the larger shops, there are also a lot of local people who make a living from stalls selling jadeite products.

Dong Shutang, 31, owns a jade stall in Linyun Jewelry Market, one of the largest jewelry markets in Tengchong.

The prices for items sold at his stall, both for retail and wholesale, range from less than a 100 yuan to several thousand yuan per piece.

According to Dong, he can sell about 60 pieces a month, from which he makes on average 5,000 yuan a month.

Several of his family members are doing the same business, too. Dong used to be a vendor of amber, but turned to jadeite business two years ago with an initial investment of about 80,000 yuan. "Doing the business gives me greater freedom compared with working as a migrant worker in other cities, although it required a relatively big investment," explains Dong, who tries to limit his inventory to reduce the risks.

The local jadeite industry has experienced a slowdown over the past few years and adjustments are being made to suit the new market trends, according to Lu.

In recent years, the local government has strengthened policy support for the industry, including constructing a high-end jadeite industrial park and boosting the jadeite carving industry and introducing more domestic and international jewelry brands, jade carving masters and skilled craftsmen to the city.

A jewelry college has been established with the approval of the Ministry of Education, which can play key roles in industrial development in areas such as brand building, talent cultivation, and academic exchanges.

"The root remains and Tengchong still has special advantages, even though some problems need to be solved in the future," Lu says.
