The protagonist's native family has a strong desire to control. Since the protagonist is the only son of the Lin family and will need to take over the family in the future, all future paths are planned for him without regard to the protagonist's feelings. By chance, his father asked the protagonist to go to Qingcheng to investigate the tea merchants manufacturing and selling fake tea. Then I picked up a nightingale. The nightingale cannot be imprisoned, which is a metaphor that the protagonist will eventually leave the cage. Later, I met the girl I liked and saved each other. Finally, after entering the officialdom by mistake for many years, he resigned and lived in seclusion.
Intention: love freedom
