First of all, economic law and civil and commercial law are not the national key disciplines of the two universities. Hua Zheng has a doctorate in economic law, and so does the Civil and Commercial Law of China University of Trade. The strength of the two is basically the same, but the Civil and Commercial Law of the University of Commerce is a key discipline in Beijing, which may be better.

Secondly, in terms of employment, both schools are very good. Comparatively speaking, judging from the employment ranking released recently, the employment of ITC is better, especially in the law school of ITC, which is extremely rare now that the employment of law is relatively low.

Thirdly, in terms of difficulty, both universities are popular universities, and the difficulty of Trade University may not be lower than that of China politics, but if China politics is as exclusive as you said, it will undoubtedly increase your difficulty. At least I know that the selection of Trade University is absolutely fair.

Of course, you have relatives in Shanghai, and you may want to work in Shanghai, so it may be better to choose Huazheng from this perspective. However, considering that you want to hit it with one blow, you obviously don't want to be affected by external factors such as unfair enrollment. In the case that the examination difficulty is almost the same, and the academic strength and employment and trade university are not inferior to that of China government, or even better, it may be a correct choice to give priority to Fair Trade University.
