Introduction to Niutou Road: Niutou Road has 210 steps, and the steps are surrounded by cow skulls. In the tradition of the Jinuo people, the sign of a man's adulthood is whether he can hunt a cow alone. Cutting off the cow's head and placing it on both sides of the road means that you have become an adult. Therefore, the number of cow heads represents how many adults there are in the clan. Man, when foreigners see these cow heads, they don’t dare to attack the stronghold easily.
