Due to a sudden change in the workplace, Lu Zhou began to interact frequently with four women with very different personalities. Independent life stories, hidden emotional scars and struggles are intertwined into a criss-crossing urban symphony. Together, they face career pressure, emotional confusion, family ties, and growth challenges. They grow individually and influence each other, and eventually understand that companionship, understanding, and self-identity are the most precious things in urban life. The book uses a multi-line, humorous and compact style to perfectly integrate personal growth and urban life. Each volume focuses on a different main line but echoes it before and after, and finally ends successfully in an emotional climax.
