In 2015, Hala was officially removed from the list of poverty-stricken villages.

Besides helping increase villagers' incomes, the village has also been focusing on Daur ethnic folk art, such as Daur folk stitchwork, songs and dances.

In June 2019, the province's first Daur intangible cultural heritage experience hall opened to the public in the village.

So far, it has received more than 30,000 visitors.

The changes in income inspired more young villagers to return to their hometown, including Kang Jian.

Kang, 30, opened a factory in 2018 to produce Daur aimen tea.

In 2019, the revenue of the factory reached eight million yuan, and helped 140 families in the village increase their incomes.

"Daur aimen is a traditional food for all Duar people, and we grew up with the fragrance of the plant," he said. "I hope I can carry forward our unique ethnic culture through my own brand.
