Temporal preexistence means that one thing exists before other things in time，and logical preexistence means that one thing is more fundamental in nature than other things. Inspired by Mr. Zou Huazheng，I was prompted to study the issue of Hegel's logical preexistence，thus deepening my understanding of western classical philosophy. Mr. Zou Huazheng's academic influence is mainly manifested in：1.From the triunity of Hegel's ontology，epistemology and logic to understand the development of the history of philosophy，and from the logic of unified and gradual thinking development to understand the history of philosophy. 2.Attach importance to the combination of history and theory，study Marxist philosophy principles and promote philosophical innovation with strong philosophical history and solid foundation of familiarity with classical works. 3.Adhere to the independence of thought and academic uniqueness. 4.love philosophy and devote oneself to philosophy cause. In the past 30 years，the philosophical research of Jilin University has revolved around the reform of the philosophy textbook system，the transformation of philosophical thinking mode，and the major contemporary turn of philosophical research，including the issues of western political philosophy，social development theory，cultural theory，etc. Made an important breakthrough and had an important impact. It is inseparable from the fact that philosophers such as Gao Qinghai and Zou Huazheng attach great importance to drawing nutrients from the history of philosophy，proceeding from the fundamental problems of philosophy and the logic of the development of philosophical thoughts，and the fine tradition of looking for new academic focus and breakthrough.
