The main content of this program: fan Chengjin graduated from University for ten years, but he is still at home. The daughter does not work at home every day, when the parents are also very anxious, but as long as said to find a job, the daughter is anxious. Fan Chengjin also has her own theory, saying that it should be considered in combination with personal development and life planning. In addition, she said that her current physical condition does not allow her to go out to work, and she is nervous when talking to strangers. This is a psychological problem that needs treatment. Fan Chengjin's parents are nearly 70 years old, and they can't afford to support their daughter any more. How to persuade her to go out to work has become an old couple's worry.
