Not that there are nine springs. There are two meanings. 1. Jiuquan: deep underground. The place where the dead are buried is in the underworld.

2. There are nine deep places, generally referring to the abyss.

The source of the Korean poem "Seven Sorrow" reads: "In the dark, there is a long night platform."

For the sake of your children, do the ritual of keeping fit and dying, I will ~, but I will also close my eyes. (Yuan Guan Hanqing's "Dou E Yuan" is the fourth fold)

"Jiuquan" is a quantifier, and the nine words below Jiuquan have the meaning of "limit" just because it is the largest number in the singular. Jiuquan refers to the deepest underground, the deepest.

The word "Jiuquan" has a history. Ancient laborers learned from the experience of drilling wells that if they dig deep underground, there will be springs. Groundwater oozes from loess, often with yellow color, so the ancients called the deep underground "yellow". In ancient times, there was a superstition that people would go to the underworld after death, and the underworld was deep underground, so the word "nine" was matched with the word "spring" to become "nine springs"
