What are the four poles and five mountains in ancient China?

Optimus Prime in Quadrupole Ancient Myths and Legends. "Huainanzi Lan Mingxun": "In the past, the four poles were abandoned, Kyushu was cracked, the sky was not covered, the land was unfamiliar, the fire was not extinguished, the water was endless, the animals ate people, and the birds took the old and the weak. So Nuwa refined the five-color stone to make up the sky, and broke the foot to stand four poles ... Tian Bu, four poles are positive. " Hou Qing's "Quasi-four cases of changing yuan and offering thanks to courtiers": "Jade Qing is still nine layers of stones; Build a mountain of work, and Wei Kun is at the four poles. "

The five mountains are Mount Taishan in Dongyue, Mount Hengshan in Nanyue, Huashan in Xiyue, Mount Hengshan in Beiyue and Songshan in Zhongyue. The theory of five mountains first appeared in Li Zhouguan's Chunda Bo: "Serve the country with blood and sacrifice five mountains." Zhou Li was written at the end of the Warring States Period, and it was a fusion of Confucianism, Taoism, Buddhism and Yin and Yang. Therefore, we think that wuyue Thought is a mountain worship formed by the blending of the four gods since Xia and Shang Dynasties and the five elements concept in the early Warring States period.
