Teacher Sun Xinkuan gave a wonderful lecture on the topic of Concept of Civil Law—The Beauty of Private Autonomy and the Burden of Self-responsibility . More than 150 students from the Law School listened online. The lecture was presided over by Mr. Li Dejia of Law School.

At the beginning of the lecture, Mr. Sun took Articles 148 and 6 of the Civil Code as examples, starting from the distinction between rules and principles in civil law, and leading out the theme of the lecture.—"The concept of civil law", and briefly explained the importance of the two concepts of "private autonomy" and "self-responsibility" in civil law.
