Adu once said that it is more difficult to be a singer than a "contractor". Last year, he got tired of performing everywhere and suffered from gastric ulcer. He was ill for more than a year, but fortunately he is used to it now. Actually, the "contractor" in Singapore is a little different from that in China. He was actually a technical director at that time. When he was a contractor, everyone called him "auntie". Waiting for the construction workers to get off work every day, I sang loudly to the music on the car in the open construction site, accompanied by only a large group of stray dogs. I guess that's when I shouted dumb. When I was a "contractor" on the construction site, my favorite song was English.
