The couplet hanging on the pillars of Kaiyuan Temple in Quanzhou, "This place was called the Buddhist country in ancient times, and all the streets were filled with saints", was written by Zhu Long-term living and giving lectures in Quanzhou, a philosopher of the Southern Song Dynasty.

Quanzhou is the first batch of national historical and cultural cities, known as "Zou Lu on the seashore", an important place for Heluo people to cross borders in history, and known as "the largest port in the East".

Quanzhou is now called "Museum Capital of Southeast Asia" because it once gathered 10 religions. Of course, Confucianism, Buddhism and Taoism are the most important representatives.

Zhu's Neo-Confucianism Thought

Neo-Confucianism, also known as Taoism, is a theory aimed at studying the meaning of Confucian classics, that is, the so-called study of righteousness.

In the Song Dynasty, Zhu's academic attainments were the deepest and most influential. He summed up the thoughts of predecessors, especially Neo-Confucianism in Song Dynasty, and established a huge Neo-Confucianism system, which became the representative work of Neo-Confucianism in Song Dynasty. His achievements were praised by later generations, and his thoughts were regarded as official studies, while he himself was mentioned as a saint with Confucius and was called "Zhu Zi".

Zhu wrote The Original Meaning of the Book of Changes, listing the images of Heluo and congenital, and edited The Book of Changes with his disciples Cai and his son (Cai and Cai Shen), explaining the theory of Heluo and congenital, which was used by later generations to explain Zhu's innate thought of Heluo.

In Yuan Dynasty, Ming Dynasty and Qing Dynasty, it has always been the official philosophy of the feudal ruling class, which indicates that the ideology of feudal society is more complete. In the second year of Yuan and Qing Dynasties (13 13), the imperial examination was resumed, and it was ordered that Zhu's Notes on Four Books and Sentences should prevail, and Zhu Weike cited the procedure. In the second year of Hongwu in Ming Dynasty (1369), Zhu et al. "passed the note as the Sect" in the imperial examination.

Zhu Xue became the spiritual pillar to consolidate the ruling order of feudal society. It strengthened the "three cardinal guides and five permanents" and hindered the later changes in feudal society. Zhu's theory also had a far-reaching influence on Wang Yangming's psychology in Ming Dynasty. Wang Yangming's thought of unity of knowledge and action is a breakthrough on the basis of Zhu's philosophy.
