Tourist visa to China with invitation by a Chinese

Are you married to the Chinese? if yes, he need to send to you an invitation letter, sponsorship, copies of his Chinese ID card and his bank certificate for visa application. Your marriage certificate and the birth certificate of your child are required as well. And there is a possibility that the visa will not be good for one year. But if you are not married yet, it is difficult for you and your child to get a tourist visa to China.
