During the performance, people who really know their opera can often be seen with their eyes closed, listening intently to the sounds of symbolism. The reverberating boom of the large gong announces the entrance of a high-ranking character. When the crisp "thwong" of the small gong rings out, the connoisseur knows to expect the entry of a boy or girl.
表演時，只見內行的觀眾有時竟閉起眼睛來聽戲，聽到長槌慢慢輕敲大鑼，就知道是有身份的人物要上場了，至於敲起清脆上揚的小鑼聲，必定是小生或小旦輕快地出場了。
