I want to ask how to apply China visa for one year or two year

Lim, then you can try to apply for the Q1 type from the CVASC centers in Malaysia. You should submit your passport, application form, a recent passport photo, your marriage certificate, invitation letter from your wife and a copy of her Chinese ID card. If you get the Q1, you should change it into a temporary resident permit within 30 days after you arrive.
