I graduated from China Southern Airlines. Obviously, the economy and management of China Southern Airlines are better than that of He Hai. Check the ranking, the professors of economics and management of China Southern Airlines are still very good. However, what you are talking about is the comparison between two schools and two majors. Every major is the same. Every year, some people find good jobs, while others find unsatisfactory jobs. This is mainly due to many subjective factors of students. Generally speaking, the international trade of China Southern Airlines may be slightly better than that of He Hai.
The undergraduate courses of these two schools are located in Jiangning District, south of Nanjing. Two schools that are basically close together.
