I'm sure you've seen a lot of walls in the lake. It's a big piece of them. If you go and feed them, they'll come and eat. And when you swim in a bunch of walls, what does it feel like?
Recently, in Zhejiang Wenzhou, a friend of the Internet raised a dog who took the dog to a spot to look at the wall. Some of the food they brought was fed to the Wall. I didn't think after seeing so many walls, the dog jumped, swimming in a bunch of walls. It's just that where the dog swims, it's like it's just around the dog.
Dogs can't be happy with so many walls. They say that the walls are lucky, that you and all the dogs will be lucky!
