My mother is from Chinese mainland, my father is from Taiwan Province, and my child is 0/5 years old this year. What are the procedures for changing to a mainland household registration?

You don't need to give up your citizenship in Taiwan Province Province, because you don't have to pay tuition for primary and junior high schools in Chinese mainland, but you can take 20 points for high school and undergraduate courses, and you can live in Chinese mainland as long as your Taiwan Province passport and Taiwanese certificate remain valid.

Moreover, you can work in Taiwan Province Province in the future, making money faster, and if you are sent to work in the mainland, your salary will be higher.

You can go abroad at will in the future, and you can also go to Taiwan Province Province as a relative at any time.

The advantages outweigh the disadvantages. Don't switch back to the mainland, or your children will hate you in the future.
