The purpose of this study is to review the current status of Korean studies education and research in China and to seek the direction of development of Korean studies education and research in China. Although Korea and China are geographically close, the discussion began in that it is necessary to examine the problems and the direction of continuous development of Korean studies in China at a time when research and education related to Korean studies in China are shrinking due to recent problems. This paper first reviewed the opening status of Korean language departments in China, and then examined the opening status of graduate schools related to Korean studies and the establishment status of research institutes related to Korean studies. Through various considerations related to Korean studies, it has pointed out the problems that have emerged in the development process of Korean studies in China so far.

As an important control station for the mainstream of the lower reaches of the Yangtze River, studing the runoff change characteristics in dry season at Datong Hydrological Stations can provide a comprehensive grasp of the hydrological conditions in the lower reaches of the Yangtze River. This study uses linear trend method, Mann-Kendall method and wavelet analysis method to analyze the dry season runoff change characteristics at Datong Station, and the following conclusions are obtained: the average flow in the dry season at Datong Station has shown a significant increasing trend and a significant change period, while the first main period is 35-year; for the typical dry months, there is no significant increasing trend in December, but the increasing trend is significant in January and February; The dry season runoff at Datong Station accounted for a significant increase in the proportion of the entire year since 2003.
