What do you mean, the avenue leads to the river, flowing through ancient and modern times?

Familiar with ancient and modern knowledge

Daoguan means that Confucius' thought is the best in ancient and modern times, that is to say, it is unprecedented. But "infiltration" is different. As the name implies, it means infiltration. Ancient and modern refers to ancient and modern. Taoism throughout the ages pays more attention to explaining the meaning of vertical coherence, that is, Confucius' thoughts and knowledge run through the ages, and his theories and viewpoints are related to the past, the present and the future. There are also some people who think that Guan and Guan are interchangeable words. However, looking at the two memorial archways in Chaotian Palace, the plaques are "Depei Tiandi" and "Taoist Temple Ancient and Modern", while Wu Daozi's classic comments are "Deyi Tiandi" and "Taoist Temple Ancient and Modern". And "Pei" and "you" mean the same thing. Are they also common words? It can be seen that the theory of interchangeable words is a bit far-fetched I thought Zeng Guofan didn't want to stick to the traditional expression, but deliberately played and created new ideas.
