These two people are both awesome figures, but although they are both economists in name, they also belong to different fields. It can be said that Lang Xianping's popularity among ordinary people is obviously higher than that of Zhang Wuchang, and Zhang Wuchang's reputation in the industry is also very prominent. He is a Taishan figure in China's economic circles. In fact, Zhang Wuchang did not completely agree with Lang Xianping. Zhang Wuchang is a pure academic master. He said of Lang Xianping: "He is engaged in management."

You can ask people who are not professionals around you. Most of them have no idea who Zhang Wuchang is, but when it comes to Lang Xianping, they have heard about it. But what is rare is that a Nobel Prize winner like Coase has a very special relationship with Zhang Wuchang.
