Opening remarks:
In 1989, Mr. Ye Jiaying taught a new round of courses on the history of Chinese poetry at the University of British Columbia (UBC) in Canada. From the "Book of Poetry" to the end of Li He, Mr. Ye spent one semester systematically telling the history of poetry from the pre-Qin to the Tang Dynasty. At the end of the course, Mr. Ye retired, which can be called Mr. Ye's final work at UBC.
