Sime Nkemeni Darrin, an overseas doctoral student in Kaifeng, Henan province, is a big fan of Chinese culture.
Majoring in traditional ethnic sports at Henan University, Liu came to China in 2017 from Cameroon.
"I came to learn Chinese martial arts, but it was the opera that attracted me in the end," he said.
Originating in Henan province, Yuju Opera is one of the country's major opera types.
"It's not only a kind of play with music. I felt closer to Chinese culture by learning and playing it," Liu said.
