[Explanation]: This refers to the two mythical stories of Nuwa refining the five-color stone to mend the sky and Xihe bathing the sun. Later, it was used as a metaphor for man's ability to overcome nature. It also describes great deeds.

【Idiom Story】:

In ancient times, there was a great battle between the god of water and the god of fire.

The co-workers were defeated, and they were so angry that they crashed headlong into Buzhou Mountain in the west, and Buzhou Mountain was damaged.

Buzhou Mountain is a big pillar that supports the sky, and as soon as the big pillar is broken, the sky collapses a large piece, and the ground also collapses a lot; At the same time, mountains and forests caught fire, floods flowed, and terrible disasters occurred in the world.

Wa, the goddess who created all things in the world (Nuwa is a native of Shexian County, Handan City, and the Wa Palace is located in Shexian County), selected many colorful stones in the great rivers, set up a fire, smelted the stones into molt, and then used this molten liquid to repair the damaged sky.

She killed an indescribably large turtle, cut off its four feet, and set them up as four pillars of heaven in all directions to hold the heavens. The ashes of the reeds left over from the fire were also used to stop the floodwaters. A catastrophe began to subside.

Xihe, the goddess of the sun, gave birth to 10 sons, that is, 10 suns.

They live in OOCL's Yugai. There is a big tree there called "Fuso", so the name of the place is also called "Fuso".

This big tree is thousands of feet high, and 10 suns live on this big tree.

They have one a day and take turns to be on duty in the sky.

In the morning, no matter which sun is on duty, they are accompanied by their mother, Xi and the car. The car was spectacular and was pulled by 6 dragons.

There are a total of 16 stations from the starting point of Tanggu to the end point of Menggu, which is exactly a day's journey.

When the car arrived at the 14th station of Beiquan, the sun had to get off the car and walk, and his mother Xihe rushed back to Tanggu with an empty car to prepare for her son who would be on duty tomorrow.

Every morning, when the sun on duty leaves Fuso, before boarding the dragon car, he must take a bath in the salty pond.

Xihe also often took his sons to take a bath in Ganyuan in the southeast and overseas, the water in Ganyuan was very sweet, and Xihe washed his sons one by one clean, bright and bright.

Ordinary people describe the incomparable great feats, they borrow the two stories of "Nuwa mending the sky" and "Xihe bathing day" as metaphors, called "mending the sky and bathing day".
