I still remember that Qingqing asked Meng Huai to find an old man in his sixties. Meng Huai came back and said that after searching for a long time, he could not find the old man selling his sixties. I laughed so hard that my stomach hurt. I thought I had seen it wrong at first glance, but I turned back and looked at it. Meng Huai, a mentally retarded child, laughed to death.
