Why did Liu Chang get married so early?

Liu Chang's wife Wu Zijia is a commercial photographer. Some people say that she is a rich woman, but Chang Lu did not respond to this question, probably because she wanted to leave some privacy for herself. However, Liu Chang chose to get married so early, probably because he really likes Wu Zijia. Otherwise, most boys will not be particularly anxious, and Wu Zijia is also a very talented person, and at the same time he can understand Liu Chang's work, so both of them can.
