A folk artist cleans the costume for the lion dance rehearsal in Yongdeng County, Lanzhou, capital of northwest China's Gansu Province, Dec. 22, 2019. Lion dance is a traditional performing art of China. Yongdeng Lion dance, a local style of lion dance known for its distinctive and complicated move, was listed as the intangible cultural heritage of Gansu Province in 2011. The lion costume, supported by wood strips inside, is approximately 2.8 meters long and 1.8 meters high, which makes the dance a demanding job for performers. (Xinhua/Ma Ning)
