Ethan Jacobson, a 26-year-old part-time dancer and business owner from Utah, is one of them. Impressing the audience with several hip-hop dances and roller-skating performance on stage, he said he has gained a "breathtaking experience" while enjoying the people, scenery, food, culture, history and basically everything in Shanghai.

"It is incredibly beautiful, and everyone has been so welcoming, loving and nice. No matter what style of dance we are doing, it is a universal language like music, and we don't have to speak it to communicate. Dancing is a way that we all can express ourselves and different emotions. It's so cool to me that I can come to China, dance with people here and feel a deep connection with them," he said.
