What do you mean by this peak?

When the sky and atmosphere are swept away, the pillar of the world is the peak, which means that the diffuse atmosphere sweeps away the mountains and has since become the pillar of the world. The sky is overwhelming, and this mountain is the pillar of the world. From the late Qing Dynasty scholar Niu Zhaolian's "Climbing to the Top of the South Peak in Hua Yue", the whole poem is: breaking through the clouds, the Tian Yang pond is dissolved, and the mountains are empty, making this peak the mainstay of the world. It means: stepping on the heavy white clouds and looking up at the water in Tianchi, the diffuse atmosphere replaced the mountains and then became the mainstay of the world. Writer Chen's novel "White Deer Plain" created a descendant of traditional literati, traditional morality and traditional personality. This man is Mr. Zhu. Fictional characters abound in the novel, but only Mr. Zhu has a prototype, which is Niu Zhaolian, a thinker, philosopher, educator, social activist and great scholar. Niu Zhaolian entered a private school at the age of nine and never forgets anything. The villagers called him a "prodigy". At the age of fifteen, he took the county exam and won the top prize. At the age of twenty-two, due to his outstanding talent, he read books on Confucianism, Buddhism, Taoism, military affairs, agriculture, finance, astronomy, geography, medicine and divination, so Niu Zhaolian got the reputation of "genius in cattle".
