He has produced the documentary series Breakfast in China, known for its distinctive personal style. With a lighthearted and lively tone, the series explores breakfast foods nationwide, but on a deeper level, it reveals the everyday joys and sorrows of ordinary people.

In contrast to Breakfast in China, where each episode runs for about six or seven minutes, Market's Legends features 30-minute episodes focusing on five different stories that take place within the same market, with fresh impromptu plots.

"The market is a mosaic of stalls, each with its own unfolding story. ...These stories coexist on the same plane. It may lack a traditional narrative arc or continuous character relationships. Everything happens in fleeting moments," Wang Shengzhi explains.
