As China belongs to the civil law countries, it will be a difficult adaptation process to study law in Britain and the United States. Because of the great differences between the common law system and the civil law system, it naturally involves the differences in the legal education system.
Of all the civil law countries, Germany is naturally the best. France and Japan are also good choices.
However, regardless of the common law system or the civil law system. In fact, the legal system is not as good as technology. It can be said that the computer level of the United States is higher than that of China, but it cannot be said that the legal level of the United States is necessarily higher than that of China. Therefore, when choosing a destination for studying abroad, we should also consider the development in China after returning to China. For example, if you are going to do theoretical research after returning to China, then going to Germany is naturally the best choice. If you want to be a lawyer, America and Britain are better. In Japan, theory and practice are relatively general.
In terms of cost, universities in Germany are free, while the cost of law study in the United States and Britain is relatively high. LLM courses cost about 400,000 RMB per year. Japan is relatively cheaper. But to study law in a non-English speaking country, you must be prepared to learn another foreign language.
In short, choose according to personal circumstances.
