Guo Ziming is a solid, cold outside and hot inside . Because his younger brother went astray, he regretted his whole life. Therefore, he determined to serve the society and take the rescue of unscrupulous young people as his own duty. After graduation, Guo Ziming joined a social youth center and became a social worker. Although he is full of enthusiasm, but there is always a distance between his ideal and reality. He often has to face the rejection and insults of unscrupulous teenagers and their families, as well as the intimidation of the underworld and the ignorance and misunderstanding of social work by the general public, which make him work at work. I often encounter a lot of setbacks.
