Yang believes that although China and Latin America have enjoyed closer relations in recent years, exchanges and understanding could be improved.

During the nationally televised CCTV Spring Festival Gala this year, many people learned about El Condor Pasa for the first time through a performance by Chinese and Peruvian artists.

"This song has instantly brought the peoples of the two countries closer together," Yang says.

On sunny Saturdays, the choir often practices at a pavilion in Beijing's Ditan Park, a popular scenic spot for foreign tourists. Once, they encountered some Mexicans, who upon hearing their singing, were reluctant to leave.

"We immediately sang Cielito Lindo (Lovely Sweet One) and Besame Mucho (Kiss Me a Lot) for them. They said they were so touched to hear songs from their home country in China, and that the performance was so touching and heartfelt," Yang says.

In March 2019, several members of the choir and their friends traveled to Latin America, visiting Mexico, Cuba and Panama, where they communicated through songs.
