On the day Du Han passed through and became a refugee from Liaodong, the system popped up a window [asking the host to destroy Ningyuan City within three days]. Looking at the imperial guards sent by Chongzhen, he picked up a shovel and smashed it at the Liaodong General Military Mansion: "Does Lao Zhu want face? Jian Nu has a saber on his neck and is still playing party politics!" When Nurhachi came with the Eight Banners to surrender, Du Han directly took out the "Five-Year Industrial Plan": "Old Nu, If you kneel down to learn steam engines, I will make you the manager of the Northeast Region! "Historical records say: In the winter of the sixth year of Tianqi, the Hongyi cannon suddenly turned its muzzle and destroyed the Forbidden City. Chongzhen found a note left by Du Han in Meishan: "I can't repair this broken ship, so I will tear it down and rebuild it!"
