What kind of experience is it to watch Aidou's concert?

I went to the Bird's Nest to watch Hua Chenyu's concert. As soon as he opened his mouth, he burst into tears, because I felt very moved, and it was worthwhile to run all the way from Ningxia to Beijing. When ten thousand people sang in chorus, he sat at the piano and looked at everyone. I suddenly feel that it seems like five years have passed in that moment, so I don't regret it and am very satisfied.
