the tributaries - one with his father at a young age and another lead by himself. There, as early as 1580, he echoed the Jianzhou Jurchen elite's frustrations with the Ming officials in Liaodong. He established his grievances that the Ming officials were corrupt and often interfered with trading. However, the Jurchen were not viewed as a threat at this time by the Ming. The change of the name from Jurchen to Manchu was made to hide the fact that the ancestors of the Manchus, the Jianzhou Jurchens, were ruled by the Chinese. The Qing dynasty carefully hide the 2 original editions of the books of "Qing Taizu Wu Huangdi Shilu" and the "Manzhou Shilu Tu" (Taizu Shilu Tu) in the Qing palace, forbidden from public view because they showed that the Manchu Aisin Gioro family had been ruled by the Ming dynasty.

Fushan was also a primary location for Jianzhou embassy members who were conducting tributary missions to stop for entertainment and refreshments. In 1618, Nurhaci's forces captured Fushun. This escalated tensions and in 1621, the Jianzhou
