Zhang Zhentian found that no matter how he talked to his wife, he couldn't get through to her. He knew that ideological education was no longer effective. He now had to start thinking of other ways to convince her, to get her to agree to his son being with this girl. He couldn't bear to separate them himself. He felt that only those who are in love can happily spend their lives together. It's better than seeking parents' approval to choose a lifelong partner; a marriage without love would never be happy.
