Cai Guoqing's wife Qin Juan is from Guizhou. She used to work in Qingfeng Lane Teahouse in colorful Yunnan. At that time, Cai Guoqing claimed that she was single, so she could not rule out the possibility that Phoebe Cai Xuan was an illegitimate child of two people, but the news could not be confirmed.

Previously, Cai Guoqing had exposed his two feelings. The first girlfriend is an American girl named Ace. The two met because of their performances, and they had a long-distance relationship for five years, but finally Cai Guoqing gave up the idea of going to the United States to marry him. The second girlfriend, Ruiting, is Swiss, and finally broke up because she couldn't solve the problem in different places. Since then, Cai Guoqing's marital status has been a mystery. It is said that even friends in the circle have only seen his son, but have never seen him take his wife out.
