I am a Taiwanese and I feel desperate about my future living in this country, what can I do to make my life better?

Think of a tree that grows on the edge of an awful, rocky cliff. It does a ton of tiny things to make its life better, adding the small changes up over time until its roots have cracked the rocks around it and made soil. Find really cheap hobbies to keep your sanity, like buying colored chalk or paint and make art for 10 minutes a couple of days each week. Choose a subject that fascinates you and read from a book about it for 15 minutes each day until within a few years you are an expert. These are just ideas to keep your sanity and maintain your individuality as you struggle to make a living. I don't know what you can do about a job and food.
