From saving his life to finding a little money, then settling into a small fortune, and then slowly coming up with some ideas, how does this humble protagonist rewrite history and stir up troubles? Can the experience of later generations of liberal arts students really be used to promote China's modernization in advance at that time? This novel and its characters are purely fictitious.
