According to the "Kunming County Zhi" record: in the early years of Jiajing in the Ming Dynasty, Jushi Zhao Lianyin was practicing in Qingfeng Pavilion. Qingfeng Pavilion was located on the Luohan Cliff in Xishan. There was no water to drink. He took the cow to the mountain and licked the water every day, never interrupted. The scalper was in the water for more than 20 years, and the calf became an old scalper. One day, the cow suddenly died, its falling place rock fell into a well. The well water is clear and the water is not dry in the year of the drought, and the water is not overflowing in the leap year, which solves the problem of Zhao Jushi's daily water use, which makes him relieve the trouble of lack of water. Xiaoniuquan also spread the legend of a Xiaoniu rescue mother in the folk. In the past, there was a Zhang butcher in Kunming, Yunnan, who bought a cow from the countryside with a calf. He sharpened his knife and tied the cow to slaughter, and suddenly heard someone outside the door calling him. He put down the butcher knife and went out to see, no one, shouted two times and no one answered, then returned to the cow, but the butcher knife disappeared. Ask his wife and son, who had seen the knife, the family did not know where the knife went. He saw the calf lying on the ground, doubting in his heart, he hit the calf, butcher knife really hid under the calf's stomach. Butcher found the knife to kill the cow, only to see the calf kneeling on the ground, tears rolling down, looking at the cow's cry. Seeing this scene, the butcher was pitied, and put down the knife and stopped killing the cow. Later, Zhang Butcher took the cow and calf to the Sanqing Pavilion to serve in labor, he was sent to repair the official road. The road was repaired to Sanqing Pavilion, there was no water on the mountain, people and animals were thirsty and hard to bear, and the calf was dug into stone wells with hoofs and stones, and led to the water spring for Zhang butcher and cows to drink. Later, people called it "filial cow spring". It was really filial piety to the heavens and the earth, and the spring reported the Lord's favor.
