Chung Yuan Christian University is located in Zhongli City, Taoyuan County (about 1 hour drive from Taipei). Zhongyuan University, formerly known as Zhongyuan Institute of Technology, is good at mathematical engineering.
Donghai University, located in Xitun District, Taichung City (about 2.5 hours' drive from Taipei), is the first private comprehensive university in the modern history of Taiwan Province Province.
On the whole, Donghai University has a long history of development and relatively complete departments.
As far as the law department is concerned, Chung Yuan Christian University has set up a department of finance and economics law, with more emphasis on civil and commercial law and intellectual property law. Compared with the law department established by Donghai University, the Department of Finance and Economics of Chung Yuan Christian University has not studied public law and criminal law in depth and breadth.
Off-topic, I personally think that there is a serious gap between urban and rural areas in the development of university law departments in Taiwan Province Province, and the distribution of teaching resources (teachers, teaching materials and practice institutions) is mostly concentrated in Taipei. If you want to study law in Taiwan Province Province, I only recommend five schools: National Taiwan University, National Taiwan University, National Taiwan University, Soochow University and Fu Jen University.
