Huashou Qinglei’s introduction: There are straight cracks in the Huashou Gate, like cracks in a tightly closed door. There is a "stone lock" hanging high in the middle, and the two sides are like a big stone wall. In summer and autumn, the sky is sunny here, but there are thunderstorms in the distance. When the rumbling thunder and lightning sound waves hit the big stone wall, they will produce an echo, like the roar of thunder, so it is called Huashou Qinglei.
