In my opinion, studying civil and commercial law has opened a new world for me: First, it has further improved my logical thinking. Secondly: Let my mind have a more detailed link. Every time you analyze a case and encounter a problem, you must learn to clear your mind and learn to solve it step by step. Most importantly, in the process of studying civil and commercial law, I overturned a profound truth that I was self-righteous before: practice does not necessarily require theoretical knowledge. In the legal field, if there is no theory, there is no need to talk about practice.
