LaoQida was a Chinese textbook in ancient Korea The content of it narrated the process of several Korean businessmen who traded in Yuan Dynasty, which included journey, business, medicine, food ,etc. But Who was the writer of this book and when it was completed had not to be known exactly. People usually think that this book should be edited in Yuan Dynasty and it was very prevalent in ancient Korea at that time. LaoQiDa has different editions. And each of them had different features ,which reflected how the Chinese language was changed from Ming Dynasty to Qing Dynasty. We have known that the oldest edition of LaoQiDa was discovered in 1998 , which should be edited not earlier than 1321 and not later than 1368.This paper included four parts. The first part primarily researched some problems about LaoQiDa, such as the editions, the researchful situation and it's status in Chinese teaching history of acient Korea.The second part primarily research the oldest edition of LaoQiDa. We used some words which appeared in this book, such as DaDu, ShunChengMen, Chao, QuKou, etc., to proved that LaoQiDa was a literature of Yuan Dynasty.In the third part, we discussed two themes. The first one was about Chinese teaching in ancient Korea. The second one was situations about Chinese book commerce with Korea.
