Answer:The Fengchan of Mount Tai originated from the ancient emperors' offering sacrifices. Fengchan is an ancient ritual. According to Zhang Shoujie's "Justice" in the "Records of the Historian ยท Book of Chanting", it is explained that "the earth on Mount Tai is built as an altar to worship the sky and report the power of the sky, so it is called" Fengfeng ". The hill at the foot of Mount Tai removes the earth and reports the power of the earth, so it is called" Zen ". "Why did this seemingly simple and clear ceremony become a grand occasion for emperors of all dynasties? What's the mystery? Since the Records of the Historian, the Book of Zen Buddhism, it is almost a conclusion that Zen Buddhism began with the First Emperor of Qin. Ma Duanlin of the Southern Song Dynasty more directly criticized" seventy-two schools "that Zen Buddhism is" the view of the crude Confucians "," which is not contained in poetry books, It is not a fact ". It is precisely Sima Qian who wrote clearly at the beginning of the Fengchan Book." The Fengchan ceremony "has been more than a thousand years for those who are far away, and hundreds of years for those who have been near. Therefore, its appearance has been destroyed, and its details can not be obtained, but it is remembered that".In China's political system, Fengchan is the most grand but controversial ceremony. The historians of the ancient doubting school in the early Republic of China believed that this was purely an activity invented by Qi and Confucianism from the Warring States Period to the Qin and Han Dynasties, and used it to consolidate political power and boast of political achievements for the great and successful monarchs. However, according to archaeological data, its origin can be traced back to the Neolithic ancestors' custom of building altars for sacrifice, which is very remote. The origin of Fengchan was largely related to the social productivity and people's understanding of natural phenomena at that time. People could not accurately grasp various phenomena of nature, so they had primitive worship. Especially in the state of fear, they were more respectful of the sun, moon, mountains and rivers, wind, rain, thunder and lightning, so the "worship of heaven and earth" came into being. From the earliest sacrifice of the countryside to the sacrifice of famous mountains and rivers, The sacrifice of famous mountains and rivers is represented by "Mount Tai Fengchan".The specific ceremony of Fengchan is symbolic. Ban Gu said, "Therefore, those who have been promoted to the highest position will be promoted. The foundation of Liang's father will be broad and thick. Those who have carved stone inscriptions will be self effective. The sky is high and the earth is thick. Therefore, the height of Mount Tai will be increased to report to the sky. The address of Liang's father will be attached to report to the earth. Tomorrow's orders of the earth will benefit the world. If the height is high, the thickness will be increased." (White Tiger Tongyi) The Book of Rites and Justice says: "Sacrifice to heaven is to burn firewood, and heaven is the sun; sacrifice to the earth, bury people, and sacrifice to the moon." The original purposes and symbols of Zen Buddhism all contain a deeper consciousness: to communicate between heaven and man, coordinate the
relationship between heaven, earth, God, and man, so as to achieve the harmonious unity
of spiritual will and external behavior.
