Singing around the world is a music travel reality show produced by Sohu Video. Guo Yonghe, the producer of the program, said: "Modern people are under great pressure. We hope to travel around the world by singing, so that everyone can put down their heavy burdens and sorrows, pack their bags and travel. This is also the view conveyed by the program. " In the third season of "Singing the World", Zhang Hengyuan and Bi Xia, the super-popular students of the second season of "The Voice of China", were invited to Lugu Lake at the junction of Sichuan and Yunnan to experience a different original ecological journey.
