There are usually a pair of stone lions or bronze lions outside the palace gate, which have the function of ward off evil spirits. Because the lion is the king of beasts, it has the functions of "dignity" and "majesty".

There are three ways to carve the ball in the mouth of a stone lion:
1, the most primitive processing method, the ball is made in the mouth, paying attention to professional technology, first draw the outline of the lion's tongue and teeth, as well as the inside of the ball and the outside of the mouth with a pencil, and use professional carving tools to remove the excess stone parts until the mouth can present a long ball shape. Then remove the excess above and below the ball bit by bit, but slowly. Don't carve a big hole in the stone lion's face until the ball can come down, then polish the ball until it is beautiful, and finally carve the teeth and tongue finely, so that the stone lion's ball is carved.
2. The method is the same as above. The difference is that the teeth are directly removed, the ball is made outside, then the ball is put in, and finally the teeth are stuck with special glue for stone, then polished and carved.
3. The method is the same as above. The difference is that the ball is made into a smaller ball, and the teeth are all intact. It is to make the ball smaller and do it outside, then put it in. Finally, the place that can be put in is glued with stone professional glue, and then processed. The stone lion ball is carved.
