During the reign of Sun Quan of the Three Kingdoms, there was a man named Li Xinchun in xiangyang JinanCheng. He has a dog at home called 'Black Dragon'. Li Xinchun liked it very much from beginning to end, and liked to take it with him wherever he went, and when he ate and drank, he had to share food with it. Even sleeping must be inseparable from the 'black dragon'.

One day, Li Xinchun went out to drink, drunk so much that he couldn't rush home. So I fell asleep in the grass on the outskirts. Just at this time, he rushed to Taishou Zhengfeng to go out of the city to hunt, but because the wild grass outside the city was very high, he asked someone to put a fire to burn the wild grass. At this time, the place where Li Xinchun slept was in the direction of the downwind, and seeing that the fire was approaching Li Xinchun, the 'black dragon' quickly used his mouth to bite Li Xinchun's clothes, and kept screaming, thinking of waking up the master.
At this time, Li Xinchun had long been unconscious, and no matter how anxious the 'Black Dragon' was, he was still motionless. At this time, the 'Black Dragon' found that there was a small stream thirty or fifty steps away from Li Xinchun, so he quickly jumped into the stream to wet himself, and then quickly returned to Li Xinchun's side and hit the water on his master's body. So many times in the past, exhausted, and finally exhausted next to the master.
After a while, when Li Xinchun woke up, he found that the 'Black Dragon' had died by his side, and his body was wet! I carefully looked at the traces of the fire around me and the clothes on my body, and instantly understood what was going on! Then he cried loudly, grieving and unable to help himself. Back in the city, there was still crying, and people were in tears when they knew what was going on!
Later, this matter reached Taishou's ears, and Taishou was very touched, and he also shed tears, and said to the people around him: "The kindness of dogs exceeds that of people, if people do not know gratitude, they are really not as good as dogs!" "So the Taishou people bought coffins and clothes and buried the righteous dog 'Black Dragon'!"
This tomb of righteous dogs, which existed in the Song Dynasty, is said to be as high as more than ten zhang! How about, no less than the story of the movie 'Loyal Dog Hachiko'?!
