Xianggujing: A dog is called a dog when its hind legs are coquettish.

I like to challenge difficult problems. The difference between dogs and dogs is that their hind legs have two wolf toes that don't touch the ground. The Book of Dog Telling, also known as Badger Dog Spectrum, originated in old Beijing. I won't elaborate on other irrelevant things. ) Most old Beijingers keep dogs to bite badgers. There are old rules in this business. If you don't have a dog, you will be laughed at by your peers. When it runs, two wolf toes may catch something, causing inconvenience. Therefore, it is necessary to remove the toes of two wolves. I typed it word for word and said, = =, hope to adopt it.
