I come from China, but I am a Yamato nationality. Why do all my classmates look at me like this? I just said I was Yamato. What happened to Yamato?

Yamato is Japanese. Just like China people are Han Chinese. No way, historical reasons.

In fact, as long as you were born in China and grew up in China, you are a native of China. As long as you are of China nationality and you love the China government, you are from China, regardless of your origin or race. As for the students, why do they all look at you like that? Those are the students who can see each other when there is a game. Bottom line: No way, historical reasons.

In fact, the Yamato clan is beneficial. If you can speak Japanese (or have someone at home teach you), you can save a lot of energy by studying in Japan in the future.
