Did you encounter many duplicate names when you were growing up?

Although my name is simple, basically no one has the same name as me. Because there is not much correlation between words. I don't mind telling you my real name. My real name is Zhang Yuanyang. Zhang is based on my father's surname. Don't think I'm wordy, because many people's names are based on their mothers' surnames. Not necessarily because the door was inserted backwards, but also because the fortune teller said his mother's surname was Geely. Yuan is because of the support at home. My grandfather is the "world" generation, my father is the "mountain" generation, to our generation is the "yuan" generation, and the next generation is the "treasure" generation. This word is said to have been left in the genealogy, but I don't know the details. "Yang" was originally an ocean, because my eldest brother is Jiang and my second brother is the sea, so I want to give it to me. But because people in my mother's family were uncomfortable, they changed the sun. It is worth mentioning that my youngest brother is Ze. It's all water I basked as soon as I came out, haha.

Although there are no duplicate names in my name, I have met those with duplicate names, such as Wang Guoqiang, He Guoqiang and Zhao Dan. Only in one school, not in one class. In fact, I really want to know, if there is a duplicate name in a class, what should I call it? For example, they are all called Zhao Dan. According to the height, Zhao Dan is tall and Zhao Dan is short; according to the body shape, Zhao Dan is fat and Zhao Dan is thin. They have never met a class with the same name. The answer will never come. Wait for other friends to tell me.
