After Nurhachi conquered Shenyang and Liaoyang, he established a stable regime. As a result, Nurhachi's true nature was exposed, and he openly plundered the money of ordinary people in the street, even went to the homes of ordinary people and put all valuable things in his pockets.
Nurhachi has a policy towards the Han people, that is, "Don't act rashly if you refuse to kill the enemy". This policy probably means that if the loyal opposition rejects the Han people in Nurhachi, Nurhachi will shoot them, but the Han people who surrender will not kill them, but in the later stage, this policy will be useless.
Nurhachi also stipulated the hairstyle of the Han people. Anyone who sees that his hair is not cut according to their regulations will be brutally killed, and even many people will be drafted into the army. If there are five people in this family, Nurhachi requires that three people must join the army. If there are only three people in a family, then two people must join the army.
Nurhachi's behavior strongly aroused the dissatisfaction of the Han people, so the Ming generals and the Han people formed an army to attack Nurhachi. Although some achievements have been made and some Nurhachi have been destroyed, this incident has aroused strong revenge from Nurhachi.
Nurhachi first attacked Zhenjiang with heavy troops and slaughtered the Han people in Zhenjiang crazily. Secondly, he enslaved all the surviving Han people in Zhenjiang. Nurhachi asked the rest of the Han people to kneel on the arrow, and then practiced archery with the Han people as the target. If an arrow doesn't die, they pull it out of their bodies and give it to the kneeling soldiers until they die.
Nurhachi also increased the pressure of Han people's lives by increasing taxes. Han people are miserable, so they hate Nurhachi.
