In my memory for the childhood. I once aspired to become Wong Tin-bar for quite a while. When glancing around and finding no one’s seeing. I would take out the broken tiles and bricks, whip round and give a light shout of “Look at the dart!” Until one day, as a result of listening to The Cases of Shigong. I threw away the vinegar bottle in this way. which drove me within an inch of suffering beating. Later, after I read works of Tolstoy and others, even when I watched Wong Tin-bar played by Yang Xiaolou. I no longer threw away any vinegar bottles. So. you see. my mind not only changes all the time, but also gets enhanced by one or two levels anyhow.
