When did Lang Xianping come to China? When did you come to the mainland?

To be exact, Lang Xianping never left the mainland because his parents lived there. Therefore, I often travel between the mainland and Hong Kong. 1994 was recruited by many universities in Hong Kong, and finally "jumped ship" from the United States and became a professor at the Chinese University of Hong Kong. It should be said that from 1994, the focus shifted to China. Moreover, long before he came to work in China, he was very famous in the United States, and his bankruptcy papers ranked first in the world from 65,438 to 0,990 financial papers published worldwide. Among the 28 corporate finance papers with the highest citation rate in the world, two are his papers.
