Longwu two years (1646. In the third year of Shunzhi, Zheng Zhilong surrendered to the Qing Dynasty, but Zheng Chenggong failed to dissuade him, so he had to lead a few soldiers and horses to leave Kinmen. Soon, Emperor Longwu (Tang Wang Zhu) was captured and died of hunger strike.
Zheng Chenggong set up troops in Leyu (Little Golden Gate) and vowed to fight the Qing Dynasty. He spent several years with his uncles Zheng Hongkui, Zheng Lian and Cai Zheng in Quanzhou, southern Fujian.
At that time, the situation in southern Fujian was chaotic. In addition to the Ming and Qing dynasties, local tyrants and mountain thieves were everywhere, fighting with each other and collecting money and food from nearby people, just like local emperors.
Compared with these local forces, Zheng Chenggong's armament is relatively complete, but because the army is too big and the territory is too small, he is faced with the major problem of raising wages.
Li Yong in the third year (1649. In the sixth year of Shunzhi, Zheng Chenggong decided to send troops to the south in October after he was appointed as Li Yong's new moon. In addition to attacking the Qing army in southern Fujian, he also planned to subdue towns and villages along the road as food sources and once captured Chaozhou and other places. However, due to the uncertainty of local soldiers, Zheng Chenggong could not control the power of interest distribution, so he had to retreat angrily.
After Zheng Chenggong returned to Minnan in the fourth year of Li Yong (1650, the seventh year of Qing Shunzhi), Zheng Jiajun became a traitor. In order to expand his power, Zheng Chenggong assassinated Zheng Lian on the pretext that Zheng Lian was tyrannical in Xiamen and the people were miserable. He took over Zheng Lian's army and territory, became a veritable Marshal Zheng Jiajun, and actually acquired Jinmen and Xiamen as bases.
Li Yong ninth year (1655. In the twelfth year of Shunzhi, Zheng Chenggong was promoted to the king of Yanping County. Because the forces of Li Yong and Zheng Chenggong are far apart, Li Yong specially authorized Zheng Chenggong to set up six officials and officials in charge of administration, and allowed him to appoint official positions, one military attache and six civilian officials.
Every time Zheng Chenggong paid homage to an official, Zhu Shugui and the imperial clan of the Ming Dynasty were invited to watch the ceremony to show their respect for the system.
Zheng Chenggong also renamed Xiamen (then the center-left school) as Siming House, and built a martial arts school so that Zheng Chenggong could personally supervise the officers and men to practice.
Twelve years in Li Yong (1658. In the 15th year of Shunzhi, Zheng Chenggong led170,000 water army to join forces with Zhang Huangyan in eastern Zhejiang and launched a massive Northern Expedition. Before the army entered the Yangtze River, it was hit by a hurricane in Yangshan waters and suffered heavy losses, so it had to temporarily return to Xiamen.
The following year, Zheng Chenggong once again led a great army to the Northern Expedition. Together with Zhang Huangyan's army, he successfully entered the Yangtze River and conquered Zhenjiang, Guazhou and surrounding Nanjing. Zhang Huangyan department also recovered more than ten counties in Wuhu area, and Jiangdong was temporarily shaken.
Later, due to Zheng Chenggong's plan to slow down the troops of the Qing army, he was attacked by the Qing army, which led to the defeat of Zheng Jun and the loss of troops, including Gan Hui and other generals.
After Zheng Chenggong's defeat, he tried to capture Chongming County as a position to attack the Yangtze River again, but after a long time, he had to return to Xiamen.
The battle of Nanjing was the most important battle in Zheng Chenggong's life, but it flourished first and then declined, and ended in great defeat, which made Zheng Chenggong's great cause of anti-Qing suffer fatal setbacks.
After the failure of the northern expedition to Nanjing, Zheng Chenggong's troops were greatly weakened and he faced the problem of insufficient military food.
Zheng Chenggong decided to go to Taiwan Province Province to provide supplies for the army.
Fifteen years in Li Yong (166 1 year. In the 18th year of Shunzhi, Zheng Chenggong left Prince Zheng Jing to guard Xiamen, with 25,000 soldiers and hundreds of warships. He set out from Luowan, Jinmen, and entered Taiwan Province Province via Penghu.
After defeating the Dutch, Zheng Chenggong carried out the reclamation policy on a large scale in Taiwan Province to accumulate military provisions and actively prepare for the next large-scale expedition.
What a pity! Shortly after Zheng Chenggong arrived in Taiwan, he died in May (1June 23rd, 662) in the 16th year of Li Yong. Before he died, he shouted "I am ashamed to see my former underground emperor" and died at the age of 39.
