I have a friend in the same situation as you. He is very good at math. He said that he had no future and wanted to study abroad, but it was difficult. You have to have a letter of recommendation from a domestic teacher. Your recommendation letter is sent to the graduate tutor of the school you applied for, and then there will be a (general) wait for two months. If he calls you to talk, the success rate should be 80%, and 20% is a lot of things, including funds. In addition, foreign countries do not pay much attention to mechanical specialty. On the contrary, mathematics and business in the United States, in particular, are truly promising majors. If it's just machinery, it's better to get employment in China.

I hope the above will help you.
