Music as bridge: U.S. opera singer Carla and her "Zhiyin" friend in China

"For the U.S. and China, it starts with listening." U.S. opera singer Carla Dirlikov Canales shares with Xinhua her friendship with 94-year-old Chinese conductor Zheng Xiaoying, who she believes is not only a maestro but also a "Zhiyin" of hers. The Chinese phrase originally means a mate who knows music well, and also describes close friends that completely understand each other.
