What are some unforgettable moments or contestants on China's Got Talent?

The most memorable moment was in the second installment of "China's Got Talent" when there was a "peacock brother" named Jiang Renrui. His performance was a mechanical peacock opening the screen, very simple and not watchable, at first the judges and the audience were not very satisfied and funny. At first, the judges and the audience were not very satisfied with the performance and it was very funny. However, when they realized that he did it just to make his paralyzed partner, who has not been able to speak for many years, smile, it touched the whole audience in an instant. I also y remembered this busy daytime to support the family at night to make his wife happy and never give up!
