In Looking at Yue, why did the poet Du Fu call Mount Tai "Dai Zong"?

Out of Qilu, green peaks can still be seen. "The poem" Looking at Yue "by Du Fu depicts the magnificent scenery of Mount Tai in Shandong. Taishan Mountain in Shandong, also known as Daishan or Daiyue, is located in the north of Tai 'an City, Shandong Province. Mount Tai in Shandong was the head of the five mountains in ancient times, and the mountains lived here, so it was also called "Daizong". In ancient times, folk customs called the venerated and valued old man "Taishan Mountain in Shandong Province", expressing admiration and gratitude for the old man who had enjoyed a long reputation. Chairman Mao's friends called the people who the revolutionary volunteers gave up at will for the happiness of the people: "To die for the people is as heavy as Mount Tai" and as light as a feather.

In a word, Du Fu called "Mount Tai in Shandong" the Daizong, which was not used by most people in society. The word "Shandong Taishan" originally refers to the name of the mountain, but now it is used more as a modifier, which is rarely used by Dai Zong. Shandong Taishan, formerly known as "Daizong" and "Daishan", was renamed Taishan in the Spring and Autumn Period. It is normal to call an encyclopedia of place names by old names in poetry. Mount Tai, the head of the five mountains in China, stands in the east of China. China has always respected the East, and each generation has been called "the exclusive respect of the five mountains" and "the exclusive respect of the five mountains".

Moreover, there will be a description in the "Custom Tongshanze Chapter": "Mount Tai in Shandong, the king of mountain buddhas, is called Daizong. Wear, start also; Zong, often also. " When you climb Mount Tai, you will not only appreciate the beautiful natural scenery, but also be intoxicated with nature. You can also feel the vast natural landscape and admire its rich culture and art, especially watching the sunrise in Taishan, Shandong Province is also a great spectacle, and the sunrise in Taishan, Shandong Province always touches the heartstrings. "Closed-door Zen" is a ritual of ancient emperors. The altar building in Taishan Mountain, Shandong Province is called "He", and the altar building in South Fu Liang Mountain, Shandong Province is called "Zen".

For a long time, Mount Tai meditation was a solemn celebration in which the ancient emperor of China told the emperor about his sacrifice. Before the Tang Dynasty, only the first emperor and Hanwu emperor held Mount Tai Zen Festival. The purpose of this celebration is to show the prestige of the country to the world and deter those restless neighbors who try to spy on China. Therefore, Taishan Mountain in Shandong Province was endowed with a lofty, solemn and solemn atmosphere, and Du Fu dared not slack off and call a spade a spade. Instead, he changed his name to show his awe.
