I think i figured the answer to your depression and suicidal thoughts @KleinerWolf
You really seem to hate your Chinese background, right? And you seem to want to get back at your nationalistic Chinese parents?
Well, through the process of having children you can start eliminating your Chinese gene in the world. After about 4 generations, the gene is mostly gone.
First step you need to take is to find yourself a nice white German girl seeing as you seem to really like the culture. Book ticket to Germany, and start looking for girls like vagina was about to become extinct tomorrow. Ok, got one? Now start fucking your genes away! Have a son or daughter with her, and now they will be only 1/2 Chinese. And people say their children give them meaning, so this would surely help with depression or suicidal thoughts a little bit. Think about it, now you become a grandfather! your little grandkids will be only 1/4 Chinese :D The next step is the most important:
You will be about 80-85, with a bunch of 1/4 Chinese grandkids. They still resemble Chinese people a little bit, so you're like "fuck!". Being 1/4 something is common and can still resemble that one 1/4, but being 1/8, that is over man. That is when you are literally fucking the Chinese away. I am 1/8th South American Indian, but if you look at me i look like i am Cortez or Colombus. You see my point? 1/8th is the magical number, which means you need to become a great grandparent. At that point you will be like 80-85 years old and so tired man. Ready to take the final step into the next world. Sitting in your house watching TV, when your grandson shows up to your house and says to you "Grandpa, you are a great-grandfather!!" There you look at your great-grandson, and you realise that your life's work is complete. This little baby is whiter than Hitler. You then and there drop dead from old age and excitement.
This is both a personal victory for you and a revenge to your parents. They will be like stop fucking our genes away @KleinerWolf but you keep doing it :)
