Chaihe was originally named Caihe! Legend has it that there is also a golden gourd on the top of the pagoda on Longshou Mountain! One day a wandering evil monk came and saw a treasure on the Taoist pagoda! I became greedy and wanted to steal it! Sitting in the middle of the night! As a result, when the gourd came down, he didn't catch it and hit him on the bald head, killing him! The gourd fell into the river at the foot of the mountain and broke into pieces! You can still see golden sand in the river at the foot of the mountain! So people named the river at the foot of the mountain Caihe! Later, people discovered that no one could fish out the gold in the river, and the water had a strange reverse flow (water flowed eastward), so it was renamed Chaihe River.
