Lu dog, a Chinese word, pronounced Lú qu ? n, which means black dog. Manlu dog is a kind of dog with folded ears, which is widely distributed in the north of China. It is tall and strong, which is also known as the big stupid dog among the people. Since ancient times, people in China pay attention to culture no matter what they play. Take cricket as an example. What crab shells are green, green hemp heads, steel heads and black heads are full of charm, and playing with dogs is no exception. Obviously, calling a big stupid dog is not elegant, so ancient literati players named this dog "Manlu Dog".
