Mao was a hero in the late anti-Jin period. He painstakingly managed Dongjiang Town overseas for many years, which can directly threaten the rear area of Houjin, which is equivalent to establishing a solid defense line for the Ming Dynasty at sea.
During the apocalypse of the Ming Dynasty, Ningyuan triumphed. After five days of the Yugoslav capital war, Nurhachi withdrew his troops in a hurry. The direct reason is that the Maoists sent troops and directly threatened Liaoyang, the stronghold of Houjin.
After Mao's resistance, Jin's will was firm, and the Jiangdong defense line he established played a great role in the Ming Dynasty. The existence of Mao restrained the late Jin army from pulling the offensive front too long and too deep.
It can be seen that the existence of Mao has always been a deterrent to the late Jin Dynasty, which caused a relatively stable confrontation between the late Jin Dynasty and the Ming Dynasty, which was already a spent force at that time, and won a little respite.
But this situation was broken after Yuan Chonghuan cut his hair with the imperial sword. After Mao's death, the threat of Houjin was lifted and he could invade the hinterland of Daming without scruple. Five months after Mao's death, the late Jin army took circuitous tactics and almost won Beijing.
Thus, Yuan Chonghuan's killing Mao had a great influence on the Ming Dynasty. Although it did not directly lead to the demise of the Ming Dynasty, it was equivalent to breaking an arm of the Ming Dynasty and accelerating the demise of the Ming Dynasty.
