Draft:Yuquan (mythology)

Yuquan, also known as Yuyuan  , is a place in Chinese mythology where the sun rests.

Yuyuan first appears in Huainanzi, a collection of essays to help the Prince Liu an govern, as the name of the last stop of the solar chariot driven by Xihe. There, the sun rests until dawn. "When the sun reaches Yuyuan, is called twilight.".

According to Hanshu, Yuyuan is in a sea in the Southern extremities and borders the world of evil. Jinshu wrote "Can I not climb to the sea and restrain the east-flowing water, and visit Yuquan and invoke the day of returning to the west?

Etymology
Song Dynasty literary critic Wu Zhengzi wrote that the term yuyuan was changed to yuquan, with the quan meaning spring, during the Tang Dynasty to avoid sharing a name with its founder Li Yuan.

Location of Kuafu's death
Zhang Zhan, in his compilation of Liezi, wrote that Yugu is another name for Yuyuan. Yugu appears in Liezi as the location where Kuafu died at the end of his chasing of the sun.

The Sun Nears Yu Yuan
Ri Bo Yu Yuan 日薄虞渊, or The Sun Nears Yu Yuan is a chengyu originating from the  Jin Dynasty writer Xiang Xiu, who used it in the context of remembering the death of two of his friends. Later variations also replace Yu Yuan with other names for sunsets.

In literature and poetry
Yuyuan has also captured the imagination of many Chinese poets and writers. For example, the poet Liu Zongyuan wrote "Did you know Kuafu chased the sun to the point he could peek in Yuyuan?" in his poem Xinglunan 行路难. Li Shangyin also wrote "Xihe drives his solar chariot until resting at Yuquan, never letting the sun turn around towards the East."
