From the perspective of administration, Sun Yat-sen University is absolutely difficult to test. You should know that the CUHK government is one of the best in the country. One of the two universities with the best administration in China (the other is China Renmin University), with such high popularity and professional strength, there will definitely be a large number of powerful candidates to pursue, and the competition will be great, but there will also be high risks and high returns. Being admitted by the CUHK government is more beneficial to your future than being admitted by other universities.
Personally, I think South China University of Technology and South China Normal University are easier to test. Although South China University of Technology has a good reputation as a whole, it is strong in science and engineering, weak in liberal arts and not well-known in administrative management. South China Normal University is not very famous, and its major is not particularly strong. Therefore, considering the above factors, these two schools have greater opportunities, and the liberal arts of Jinan University is generally good.
