People like you should be happy. Therefore, my advice to you is to do your job well and realize your dream through your own efforts. Maybe this process will take longer, but you can't give up hope. One more unpleasant word: treat yourself as an orphan and shouldn't you live a good life?

I'm from Yunnan, now I'm in Beijing and my brother is in Kunming. He is almost 40 years old this year. He works hard and has two houses, one for himself and one for my parents. As long as you work hard, it is possible to be a toast in Yunnan, not to mention a house.
