Jiang Shangzi Ziya is a native of the East. His ancestors served as tribal leaders in Shun Dynasty, helping Yu Xia control water sources. Being sealed in Lu and taking the land as his surname, it is also called Lu Shang. Xia Hou, the descendants of Lu, were born in poverty. Lu Shang is a talented and ambitious person. But under the cruel rule of Shang Zhouwang, he didn't give full play to his talents. In order to make a living, he once slaughtered cattle and sold meat in Chao Ge, and opened a liquor store on the streets of Jin Meng. Time flies, Lu Shang has become an old man in his seventies in a blink of an eye, but his ambition still cannot be realized. Later, he heard that Wang Sixian in the west of Zhou Wen was thirsty, so he came to the foot of Qishan and the Weihe River in Shaanxi.

There are two versions of Lu Shang's meeting with King Wen in Historical Records. One version said that Lu Shang pretended to fish in Panxi, expecting the arrival of King Wen. On this day, King Wen unearthed hunting, passed Panxi and met Lu Shang who was fishing. When two people chat, the more they talk, the more speculative they become. Lu Shang talked endlessly about his views on governing the country. King Wen admired him and said happily; "You are the saint my ancestors hoped for!" Since then, Lu Shang has been nicknamed "King Taigong". King Wen and Lu Shang returned in the same car and named Lu Shang as a teacher. Another way of saying it is that King Wen secretly accumulated strength in an attempt to engage in business, which was discovered by Hou Hu and reported to Shang Zhouwang. Zhou Wang was furious and put King Wen in his dream (now north of tangyin county, Henan). King Wen's minister, San Yisheng, and Yao Hong knew that Lu Shang was very capable, so they invited him. The three of them discussed a clever plan: to find beautiful women, horses and treasures to show Zhou's "loyalty" to business. Greedy Zhou Wang was tricked into releasing King Wen. After King Wen returned to China, he worshipped Lu Shang as a teacher.

Lu Shang's advice to King Wen is, first of all, "Xiu De relies heavily on commerce and politics". Shang Zhouwang's greed for wine and hunting is unpopular; Zhou Wenwang banned drinking and hunting to win people's hearts. Shang Zhouwang is willing to squeeze the people, and the people are miserable; On the other hand, Zhou Wenwang implements the policy of "enriching the people", that is, collecting rent tax moderately, so that people have some savings and are interested in hard production. Shang Zhouwang lured slaves, causing resentment in other small countries; Zhou Wenwang formulated the "law of reading (searching) when the slaves are dying (fleeing) and in the famine (big)", which means: Search for slaves when fleeing, "Anyone who is a slave shall not hide fugitive slaves. In this way, Zhou's position in the vassal state was greatly improved. Even the monarchs of the two countries, Yu and Rui, are willing to settle their disputes this week, because they all admit that they are "gentlemen with benevolence". When the governors of the world heard about it, they all thought it was "ordered by the king", so more than 40 countries surrendered to Zhou. Then, Lu Shang intends to develop power for King Wen in various places. Zhou successively "chopped off the dog army", "chopped off the beard", "defeated the country", "chopped off the pole" and "chopped off the beard", all of which can be found in Historical Records Zhou Benji. There are also records of "cutting Shu" and "collecting nests" in Oracle Bone Inscriptions of Joo Won?. It can be seen that Zhou not only expanded his territory to the west, but also expanded to the south, and his power directly reached Jianghan Basin. In his later years, "the world is divided into three parts, and then the week is divided", which caused the situation of merchants encirclement, and Lu Shang's strategy was successful.

After the death of King Wen, King Wu succeeded to the throne, respecting Lu Shang as "the teacher is still the father", which means "the teacher is still the father". Lu Shang assisted King Wu. I was unlucky before school started and caught up with the storm. The vassals were very afraid. Only Lu Shang realized that it was now or never, and resolutely advised the martial artist to arise. Sure enough, I was caught off guard and was ruined by Zhou. After King Wu occupied Yindu, he distributed Zhou Wang's money stored in Lutai and grain stored in Giant Bridge to the poor, sealed the tomb of Bi Gan, a loyal minister of Shang Dynasty, and released Ji Zi imprisoned by Zhou Wang, thus winning the hearts of the people. Most of these ideas also come from Shandong businessmen.
