There are two kinds of legends:

1. In the Tianchi Lake in ancient Changbai Mountain, the day when the lotus bloomed,

Immortals from all walks of life went to Tianchi to bathe and collect lotus flowers and travel around the mountains.

One year, two of the Eight Immortals, Tie Guai Li and Lv Dongbin,

Say goodbye to the gods by Tianchi lake,

Suddenly I found a strange mountain at my feet, shining like snow and stinging my eyes.

Two immortals walked up the stone and suddenly saw a flat boulder, smooth and square, like a chessboard.

Tie Guai Li shouted, "Brother Lu is really good at this chess game." . Why don't you have a rest?

From noon to night, they can't tell who wins and who loses;

At night, the moonlight is bright, and then you can't tell the difference between winning and losing.

At dawn, a woodcutter at the foot of the mountain went up the mountain to cut wood.

I saw two old people playing chess slowly, and I couldn't help walking towards the old man who was playing chess. He looked like he didn't know how long it had been, and the young man felt hungry.

Run down the hill in a hurry, go home for something to eat, and then go back to the mountain.

When he returned to the village that day, the old people suddenly realized: This is Tie Guai Li versus Lv Dongbin!

Everyone spreads the news, spreads the news.

So everyone in Shili Village near this mountain calls it Qipanshan.

It is said that there was a black dragon king and a Bai Longwang who often watched and played chess here in ancient times. One day, two dragon kings chatted about chess. To outdo each other, they made a bet with their wife that they fought for three days and nights, regardless of the outcome. Coincidentally, at this moment, the wife of the black dragon king came to call the black dragon. The black dragon was careless and lost completely. Bai Longwang will drag away the wife of the Black Dragon King. If the wife of the Black Dragon King refuses to follow, Bai Longwang will pull hard. Now the grass here grows obliquely, which is said to be the trace left by the wife of the white dragon dragging the black dragon. In addition, the footprints of the black dragon's wife are clearly printed on the stone of Jiulong River. Later, the black dragon king overturned the chessboard in a rage and washed away the Bailong Palace with the flood. This angered the jade emperor, and a fireball fell from the sky and burned the Black Dragon Palace. So the snakes in Laotangou are black, regardless of size. It is said that they are all descendants of the Black Dragon King. The mountain where black and white dragons play chess is called Qipanshan. You can check the official information, there is no official name, mainly the first legend.
