Dakang Li, the character in the play, can be widely welcomed, especially recognized by teenagers. The reason is that, besides the acting skills of the old actors, there are almost unified rules and regulations in the speech and behavior of some cadres, which are different from those of the real ruling organization-Li cares about the people (communicates with workers), works vigorously (pursues the pioneering spirit of "freedom without prohibition") and is strict with his subordinates (does not forget to urge them after work).
