What is the immigration process of graduate students in Chengdu?

It seems that mainlanders can't settle in Taiwan Province Province now. You can check the Taiwan Province provincial authorities' policy on mainland brides in recent years on the Internet, and you will know how difficult it is for Taiwan Province provincial authorities to settle in Taiwan Province province and obtain legal status, not to mention that others are still married to people from Taiwan Province province, and as you said, they are not with their spouses, and it is even more impossible to succeed.
