Baxia, also known as the tortoise, is the old six. He has a good load and great strength all his life, and the turtle under the pedestal is his portrait. Legend has it that in ancient times, Baxia often carried three mountains and five mountains on his back and made waves in rivers, lakes and seas. Later, Dayu subdued it when he was controlling the water. It obeyed Dayu's command, pushed mountains and dug ditches, dredged rivers and made contributions to water control. After the flood was defeated, Dayu was worried that he would run wild again, so he moved to a huge stone tablet with indomitable spirit, which was engraved with the merits of water control and told him to carry it. The heavy stone tablet prevented him from walking casually. The dam is very similar to the tortoise, but there is still a difference when you look closely. Bazaar has a row of teeth, but the tortoise doesn't. The number and shape of nail plates under the dam and on the tortoise shell are also different. Bullies, also known as stone turtles, are symbols of longevity and good luck. It is always struggling to move forward with its head held high, its four feet desperately propped up, struggling to move forward, but unable to move. The pedestals of some famous stone tablets in China are carried by tyrants, which can be seen in the forest of steles and some historical sites.
