How far is Tianmu Mountain from Taimu Mountain?

Tianmu Mountain and Taimu Mountain are 400 kilometers apart.

Taimu Mountain is located in fuding city at the junction of Fujian and Zhejiang. It stands proudly on the coast of the East China Sea, where mountains and seas depend on each other, and is known as "the grand view of mountains and seas" and "the fairy capital of the sea". Taimu Mountain looks at Yandang Mountain in the north and Wuyishan Mountain in the west, and the three are in full swing. Yandang and Wuyishan are located in the main roads and are famous far and wide, while Taimu lives in the corner of the sea, and those who know it are fresh. I always thought that Mount Taimu was the Mount Tianmu in Li Bai's "Climbing in the Dream of Mount Tianmu", and I especially liked the poem "A tourist sailing will say that Japan is inaccessible to water and fog". However, when the Vietnamese talk about Tianmu Mountain, they can still see it through clouds of different depths. On a straight line leading to heaven, its peak enters heaven, topped with five sacred peaks, and casts a shadow across China. "Now we know that Tianmu Mountain is in Xinchang, Zhejiang, and Taimu Mountain is in Fuding, Fujian, nearly 400 kilometers apart.
