The children were originally quite lively. The big kid Wang Chun, around 20 years old, and Haichou started playing with each other early on. Big Brother Wang told popular mainland jokes. The child from Taiwan didn't have any of those to respond with, so he went all out telling dirty jokes, which completely stunned the older boy from the mainland.
孩子們本來就是活潑的，遇到還只廿歲上下的大孩子汪軍、海洲，早玩在一起，汪哥哥講大陸流行的笑話，台灣來的小孩無以回報，只好拚命講有色笑話，讓大陸的大孩子聽得一愣一愣的。
