Introduction to the interior of Dacheng Hall: The plaque of "Teacher to All Ages" was written in the 23rd year of Emperor Kangxi of the Qing Dynasty (1684). There are two pairs of pillar-holding couplets in the hall, both written by Emperor Gaozong in the 13th year of Qianlong's reign in the Qing Dynasty (AD 1748). The first pair is "The Poems and Calligraphy of the People's Republic of China, Yi Xiang, Spring and Autumn, Eternal Taoism, Outstanding Rivers, Seas, Taishan, Linfeng". "More than a saint." The main idea of the first couplet is: In order to let the people understand the classics, Confucius deleted the "Poems", "Books", and "The Book of Changes" and wrote the "Spring and Autumn", which is worthy of eternal praise. The main idea of the second line is: Linfeng is the god of beasts, Mount Tai is far higher than the mound, the river and the sea are vaster than the creek, and since the beginning of mankind, there has been no one greater than Confucius. The last couplet is "Qi prepares the four seasons and combines the virtues of the heaven, earth, ghosts and gods, the sun and the moon, and the teachings will be passed down to all generations to succeed Yao, Shun, Yu, Tang, Tang, Wen and Wu." The main idea of the first couplet is: Confucius's character, morality, and tolerance are incomparable and incomparable. The main idea of the second couplet is: Confucius's education of the people was even worse than that of the wise kings of the past dynasties.
