I am a fake Chinese person

I am a Chinese woman. My parents were born in the US, but their parents are from China/Vietnam.

We celebrate Chinese New Year, follow the Chinese stereotypes like no shoes indoors and eating rice and using chopsticks and stuff, but my biggest gripe is that my parents have straight up said we (I have siblings) will always be fake Chinese because we cannot speak the language.

Both my parents speak Cantonese and my grandparents speak Cantonese and Mandarin. I don’t speak either. I took Chinese classes as a kid, where most of the class already spoke Canto/Mandarin, so I was overlooked and taught nothing. in fact, I was made fun of. I took classes again in middle, high school, and college, but my Mandarin is still very poor.

I truly am upset I cannot speak the language even though I’ve been studying it for pretty much 8 years at this point. I am upset that the Chinese language in my family will die with my parent’s generation because I can’t speak it. And I truly am upset that I feel like a fake Chinese person.

So…what can I do?
