It's nice to meet you here. My parents moved here from China about 30 years ago, and I was born here, so we have a similar background but have slightly different experiences.
In many ways, I also get that feeling you describe of "That's how it is", even though I was born here. But I find it is often enough when friends or strangers just accept my stories and what I have to say, without needing to feel like they have to defend any stereotyping or racism or misunderstanding. In these cases, I find it can be helpful just to tell them bluntly that they are my experiences and I'm just asking that they listen and don't need to provide hints or commentary or anything like that.
Otherwise, I don't really go out of my own way to educate people unless they ask, because I tend to think that people who are interested like Postive_vibes89 has said, will tend to ask me anyway. And for those who aren't, a conversation about Chinese culture is likely to be uninteresting at best, and unnecessarily confrontational at worst. Some of my best friends treat me like they treat anyone else, but they honestly could not care less about my Chinese culture - they respect me for who I am, respect that we have differences, and that is really all I ask for.
So if people are interested, I think it is often quite easy because they will ask questions and show they want to know more. If people are not, it can be a bit difficult to have an in-depth conversation and they may not be as interested as we may want. But hopefully, they will also be able to respect that you have different experiences to them due to your culture, and understand that it's really important to you.
It's a challenge for sure, but I think if we all start from a place of respect of individuals, people's natural curiosity will lead to more questions and greater understanding.
