What kind of dog is the white gouhuang with a mark on his head?

This dog was born in Taolin Village, Qingxi, Tai Po, "about 1998~2003". It is a male dog with four brothers and sisters. Its mother is a white dog with black spots on her black head. And he doesn't look like the picture above. He has a pure yellow head, fierce eyes and perfect figure, with yellow spots and round spots. His tail should be knife-shaped. He is the god of war in our village, and all his dogs are afraid. Its owner is driving a dragon carriage with a loud voice; This dog is the god of war in the dog world.

It died at the hands of a hunter. It was Sunday afternoon. When we went to the town middle school by bike, they said they would kill the dog. First, the hunter used a thick wire to get it from home to the door, and there was a big fight between dogs at the door. Hunters can't stop it. I am still deeply impressed, because it often bites his hounds and beats wild boar, and several hounds are afraid to pass by it. Mainly because it seems to bite. I wonder if it's true. He was locked up for about half a year before he was killed. Once, he came out somehow and dragged a chain to fight with a bigger white hound at my door (his tongue was blue). At first, the two sides threatened each other for about half an hour. Then the hound lost its mouth and left a lot of blood. There are many examples (dogs in neighboring villages), which are difficult to describe in words.

There used to be a black bitch in my family. She was very timid and was often bitten by other dogs. In the countryside, when the bitch is in heat, there will always be several male dogs. In the end, it always wins. There is a little black dog with a tail, and its brother is often killed by it. Other big dogs are afraid to run when they come to my house. I wonder if we have this kind of dog gene near our hometown now?
