An ordinary low-level worker does not rely on background or connections, but relies on ability, choice, and persistence to rise from a monthly salary of 3,500 to the top of the industry. The starting point is: an ordinary second-level graduate, working as an administrator and handyman in a small company, with a monthly salary of 3,500, and a rent of 1,800. He squeezes into the subway every day, is scolded by his boss, and is blamed by his colleagues. There is no hope.
