Legend has it that Shang Zhouwang at the end of Shang Dynasty was a luxurious and ruthless king (see "Helping others"). "Xibo" Jichang, later known as Zhou Wenwang, was imprisoned for opposing Zhou Wang. He tried many ways to escape from prison. At that time, the capital of Zhou was in Qishan (now Qishan County, Shaanxi Province). Zhou Wenwang returned to Qishan, determined to overthrow the rule of Shang Dynasty. First, he hired Jiang Shang (Jiang Taigong), a military strategist, to actively train and prepare for war, and then he annexed several small vassal states around him, and his power gradually became stronger. Then, the capital moved to Fengyi (now near Huxian County, Shaanxi Province) and prepared to move eastward. But soon, Zhou Wenwang died.

Zhou Wenwang's son Ji Fa succeeded to the throne, namely Zhou Wuwang. Jiang Taigong continues to be a strategist. King Wu's half-brother Ji Dan (Duke Zhou) and half-brother Ji Shi (Zhao Gong) are two right-hand men. At the same time, King Wu won the support of several other governors. So he officially announced that he would send troops to cut down. The army crossed the Yellow River in Jin Meng (now the South Yellow River Ferry in Mengxian County, Henan Province) and pushed northeast, reaching the capital of Shang Dynasty (now the northeast of Qixian County, Henan Province). Because Shang Zhouwang has lost everyone's heart. The army didn't want to die for him. They fled and surrendered, and the uprising was quickly conquered. Zhou Wang committed suicide, and the Shang Dynasty was over. After more than 800 years, it became the world of Zhou Dynasty, which was called Zhou Dynasty in history.

At the beginning of Zhou Wuwang's conquest of Chao Ge, King Wu was not sure how to deal with the nobles and officials left over from Shang Dynasty and whether he could quickly stabilize the situation. To this end, he held consultations with Jiang Taigong and others. In the "Shuo Yuan Gui Fa" compiled by Liu Xiang in the Western Han Dynasty, there is such a record:

Yin Ke, the king of Wu, called Taigong and asked, "What about Naiqi?" Taigong said to him: "I love his people, and I also love black houses;" People who hate others hate others. What if Xian Liu defeated the enemy and made it more than enough? "

Zhou Wuwang defeated Yin Shang, summoned Jiang Taigong and asked, "What about their personnel?" Taigong replied, "I heard that if you love that person, you will also love his crow;" If you hate that man, you will also hate his servants and retainers. How to treat killing all the hostile elements and leaving none behind? -The so-called "Seo Woo" in the original text is a petty official with the lowest status, a housekeeper of a slave owner and a nobleman. (Yu, Wei, etc. ; Xu, Xu Li )

There is a similar record in Biography of Shangshu Daji compiled by Fu Sheng in Han Dynasty: When he died, the prince of Wu was undecided. Calling the squire, he asked, "What about going into the Yin?" Taigong said: "I heard that lovers are also black houses;" Those who don't love others, and their spare parts. "

This record is similar to that contained in Shuo Yuan. But the word "Seo Woo" is written as "Yu Xu" here. They have different meanings. Yu Xu is no longer a petty official, but a slave or criminal whose status is lower than that of Seo Woo. For example, Ji Zi, a surname, was imprisoned because of dissatisfaction, so he pretended to be crazy and was willing to be a slave, so Zhuangzi called him Yu Xu.

In addition, Han Shi Zhuan and Liu Wen also recorded the above conversation, and the contents are basically the same. Because of this legend, the idiom "love me, love my dog" came into being.

Since ancient times, there has been a superstitious custom in our country that crows are "ominous birds", and whoever falls on their houses will be unfortunate. In the Xiaoya part of The Book of Songs, the oldest collection of poems in China, there is a poem called The First Month, which means "disaster will fall on whose home depending on where the crow falls". It can be seen that the ancients hated crows more than they loved them. The so-called "love me, love my dog" is because I love that person, and even his crows don't think it's ominous and annoying. This idiom has always been used as a metaphor for pushing love. Because you love a person deeply, you love his relatives, friends and other people or other things. This is called "love me, love my dog" or "love me, love my dog".

Du Fu, a poet in the Tang Dynasty, said in the first two sentences of his poem "Li Gifts Shehong" (Shehong, place name, in today's Sichuan, Li is Li Mingfu): "The husband's house is good, and he is good at it." In the Song Dynasty, Zhou Dunyi wrote "Poems on Lianxi": "Angry crabs in the water, love dogs in the house". Li Jiao Bo Yi, written by a poet in the Song Dynasty, also said: "When the sky is clear, I look at the birds in front of the door, and people look at the black in front of your house." They are allusions to the idiom "Love me, love my dog".
