Lin Ran, an ordinary young man who broke into a big city with ideals and a little bit of cleverness, started from a terrible first job. On the stumbling road to work, he met all kinds of colleagues, roommates and friends, and got involved in workplace secret wars, love failures, family pressure to get married and trivial matters in life. With the push and pull of the high-paced life in the metropolis, Lin Ran was weaving daydreams of being a "winner in life" while being mercilessly slapped in the face by reality. However, in the years of laughter and bitterness, he gradually realized his own simple happiness. The life lines of the partners around me are intertwined, sometimes far and sometimes near, and everyone is looking for hope in the floating city. The four volumes of stories have a strict structure and are full of warmth and humor. They not only show the fatigue and helplessness of urban life, but also outline the highlight moments of ordinary people.
