Jiang Ziya
From World's Chinese Wiki
Jiang Ziyaalso known as Jiang Taigong (Chinese: 姜子牙, Pinyin: Jiāng Zǐyá) (dates of birth and death unknown), a Chinese semi-mythological figure, resided next to the Weishui River about 3,000 years ago. The region was the feudal estate of King Wen of Zhou. Jiang Ziya knew King Wen was very ambitious so he hoped to get his attention.
He often went angling at the Weishui River, but he would fish in a bizarre way. He hung a straight hook, with no bait, three feet above the water. He over and over again said to himself, "Fish, if you are desperate to live, come and gulp down the hook by yourself."
In a little while his outlandish way of fishing was reported to King Wen, who sent a soldier to bring him back. Jiang noticed the soldier coming, but did not care about him. Jiang just continued with his fishing, and was soliloquising, "Fishing, fishing, no fish has been hooked—but shrimp is up to tomfoolery." The soldier reported this back to King Wen, who became more interested in Jiang.
King Wen sent a bureaucrat to invite Jiang this time. But Jiang again paid no attention to the invitation. He simply carried on fishing, saying, "Fishing, fishing, the big fish has not been hooked—but a small one is up to mischief."
Then King Wen realized Jiang might be a great genius so he went to invite Jiang personally, and brought many magnificent gifts with him. Jiang saw the king's earnest desire so Jiang decided to work for him.
Jiang aided King Wen and his son in their overthrow of the Shang Dynasty; they established the Zhou Dynasty in its stead. Jiang was given the title (hao) of Taigong so people called him Jiang Taigong. His treatise on military strategy, Tai Gong Six Teachings, is considered one of the Seven Military Classics of Ancient China.
Jiang Ziya's seventh generation descendant (his great-grandson's great-grandson's son) was Jiang Chi (姜赤). Jiang Chi had a great-grandson named Shi (傒), who was given a piece of land in Shandong province called "Lu" (盧). He took his surname from the land. All Chinese with the last name Lu (盧) can trace their ancestry back to Jiang Ziya.
