Niuhu bronze ware is a ritual vessel made of bronze in ancient Yunnan during the Warring States Period. Its shape is a clever combination of two cows and a tiger. With a strong bull as the main body, the four legs of the bull as the chopping board, the back of the bull as a round chopping board, a tiger pouncing on the cow's tail, its four paws tightly pedaling on the cow's body and biting the cow's tail, eyeing the chopping board. There is a leisurely calf standing under Daniel's stomach, with its head and tail slightly exposed outside Daniel's stomach, which shows that Daniel sacrificed his protection for the calf. In the case of Niuhutong, the neck muscles of Niuhutong are rich, and two huge horns stretch forward, giving people a feeling of going forward and tottering, but the tiger at its end leans back and then falls back to restore the balance of the case. Daniel's calf placed horizontally under his abdomen enhances the stability of the watch case. This bronze ware is one of the largest bronzes in Yunnan, and its special combination shape makes the whole bronze ware stable in center of gravity, harmonious in size and balanced in movement. Because of its peculiar shape and novel conception, this bronze ware not only has the characteristics of the Central Plains quadruped, but also has strong local characteristics and national style. It has reached a very high artistic level and has great artistic appreciation value. It is a masterpiece of bronze works of art in China and a rare treasure in ancient China culture.
