Can't three generations be named with the same word?

It is generally impossible for this to happen. Every name has a word "seniority", which is usually one of the three names, and the remaining one is also dominated by the word "seniority". The word "generation" is different from generation to generation, and the difference between the younger generation and the older generation is reflected here. In ancient times, Chinese characters were taken according to this law. Now this rule is not very common, but because of the influence of this rule, no matter how fancy the name is, it is related to the word "seniority" of this person. Therefore, there are generally no such three generations with the same surname. Of course, this is China. In Japan, three generations can be called "Taro" or something.
