The village decided to focus on environmental protection and choose a pace of sustainable development and has undergone unprecedented changes since then.

It shut down mining and other industries that caused pollution and started to develop tourism industries. In 2018, the village was listed as a 4A class tourist attraction, the second-best rating in a five-level assessment system for the country's tourist attractions.

No garbage or trash cans can be seen from the road in the village. "The village has practiced garbage classification, and houshold garbage is collected and transported by designated personnel regularly," said Hu Bin, a villager in Yucun.

"More than 800,000 tourists visit our village each year," said Jiang. "The beautiful environment has brought us wealth." Tourism has become a pillar industry of the village, which has 280 households and 1,050 villagers.

Pan Chunlin was a tractor driver working for a stone mine in the village. He opened the village's first travel agency after the mine was closed.

"People in cities love our vegetables such as bamboo shoots," he said. Now the operating income of his homestays has exceeded 7 million yuan (about $985,600) each year, which is dozens of times more than when he worked in the mine.

From 2005 to 2019, the village's collective economic income rose from 910,000 yuan to 5.21 million yuan, and the per capita net income of villagers increased from 8,732 yuan to 49,598 yuan.

"We respect nature, and nature will never mistreat us," said a villager surnamed Gu.
