Story of the Three Kingdoms: Looking at Plums to Quench Thirst.

During the Three Kingdoms period, when Cao Cao led troops to attack Zhang Xiu in Wancheng (now Nanyang, Henan), he passed a place called Meilinpu in Fangcheng County. It was noon, sunny and hot. Cao Cao sent people to look for water everywhere and ordered soldiers to dig wells on the spot, but there was never a drop of water. The soldiers and the whole army are thirsty. In order not to delay the March, Cao Cao had a brainwave, stood on a high place, pointed to a hill in front and said, "There is a large piece of Meilin in front, bearing many plums, which are sweet and sour, and can quench your thirst." Hearing this, the soldiers drooled for a while and stopped thirsty. They all recovered their spirits, accelerated their March, and finally reached the place where there was water in front.

Jin Dynasty: Sheep carts look at Geely.

Sima Yan, the founding emperor of the Jin Dynasty, recorded a large number of maids in the harem, with nearly 10,000 maids. Therefore, deciding which concubine is lucky every night has become a headache for him. So he came up with a way, that is, to sit on the sheep cart and let the sheep walk around the palace at will, and he loved his concubine wherever the sheep cart stopped. So an imperial secretary put bamboo branches on the door and sprinkled salt water on the ground. The sheep stopped eating because they liked the taste of salt water, so the sheep cart stopped at the door of her palace. This story comes from thirty-one books in Jin Dynasty. Because of this story, future generations hope to get the attention or love of others, which is the so-called "sheep and cars look forward to good news."

Southern and Northern Dynasties: One Clothes with Water

During the Northern and Southern Dynasties, the Northern Zhou Dynasty in the north and the State of Chen in the south were bounded by the Yangtze River.

Emperor Wendi of Sui Dynasty, Prime Minister of Northern Zhou Dynasty, abolished Emperor Jingdi of Zhou Dynasty, established Sui Dynasty on his own.

Determined to destroy the State of Chen, he once said, "I am the parents of the whole country. Can I watch the people in the south suffer and not save them because there is a Yangtze River as narrow as a belt? "

Later, people used "only a strip of water" to describe that the two places are very close, with only a narrow water area.
