Wen Zhong and Bi Gan had different views on the status of the two. Some documents believed that Wen Zhong had the highest status because he was King Zhou's teacher and had extremely high prestige and influence. He controlled the core combat power of the Shang Dynasty, and he had been fighting for many years. He had pacified the North Sea and held military power. Bi Gan was King Zhou's uncle.
