The peak of Mount Tai is flat, also known as Ziyan Kong. According to legend, Confucius stood here when he climbed Mount Tai, expressing the feeling of "climbing Mount Tai and being small in the world". There is a stone inscription on the cliff: "Confucius is on earth."
The following is the title link of Xu Zonggan:
The higher you climb, the stronger you drill.
It is natural to surpass the same kind and excel.
Note: The higher the yang, the stronger the drillability.
Out of its kind, out of its kind: the language is "Mencius Gongsun Chou".
