Quick humor joke?

Pan Jinlian's relationship with the Japanese (laughing to death irresponsibly)

In those days, after Wu Song killed Ximen Qing, Pan Jinlian knew that there was a catastrophe, and hurriedly ran out for her life. She thought, it was all Ximen Qing's fault, and Simon was unlucky and fled to the East Gate. Finally, I found that there was no way out, so I had to cross the ocean and stay on a small island. The baby was born. A few years later, the baby was short and short. She knew it belonged to Wu Dalang, but what should she name it? Let's call it taro You don't believe me? Some Japanese are called Taro and Ichiro, but never Dalang, just because Wu Dalang is their ancestor. The Japanese figure is caused by Wu Dalang's genes. Mother and son live on the island. The wave hoof couldn't help feeling lonely, and made up his son's mind. Finally, the mother and son became a good thing, and people on the nearby fishing boat criticized them one after another. The wave hoof cursed: "My son is my own son, so I don't care what you do." Later, everyone called them "Japanese." The more children you raise, the more Taro thinks, why don't I set up a country and get rid of the addiction of being an emperor. When the country wanted a national flag, Pan Jinlian said, "Your father sells cooking cakes, so just draw a cooking cake on the sheet." So, the national flag was available. In order to make good luck for the old Wu family, four big characters were specially written on the flag: "Long-lasting martial arts"!
