Who is the historical prototype of Jiang Ziya?

In the Zhou Dynasty, there were two big noble groups, Yoshioka, who married for generations. Jiang Ziya is probably the aristocrat surnamed Jiang in the Zhou Dynasty. The legend that he was frustrated in his early years and fished in Weishui should have been compiled by people in the Warring States period, which is an inspirational story for tourists looking for officials everywhere. When cutting Zhou, Jiang Ziya should still be in his prime, and he is estimated to be in his 40 s

He also personally went to the business to challenge. You can see from Zuo Zhuan that you have high martial arts and agile skills. If an 80-year-old man challenges, he is likely to despair. During the Warring States Period, many unlucky people didn't get an official when they were old, so they made up a story about Jiang Ziya meeting King Wen in his seventies and eighties to console themselves.
