What are the procedures for applying for a long-term residence permit visa in Taiwan Province?

At present, in addition to getting married, I go there as an exchange student, or as an executive who invests in mainland enterprises in Taiwan. Otherwise, I can't "stay for a long time" in Taiwan Province.

you need to apply for a "mainland residents' travel permit to and from Taiwan Province". It's called "Taiwan Entry Permit". If you are a citizen of the People's Republic of China and have no immediate family members within three generations in Taiwan Province, you can't live in Taiwan Province at present. There is no way for you to enter Taiwan Province except for traveling with a group.
