As for Zheng Chenggong's eldest son, it is Zheng Jing, the father of Zheng Keshuang in the famous Duke of Lushan. According to historical records, Zheng Jing was born to Zheng Chenggong and his wife Dong Yougu. He is the eldest son of Zheng Chenggong, who can be called the successor of "Rooted in Hong Miao", so Zheng Chenggong began to focus on cultivating him from an early age.
When Zheng Jing 19 years old, Zheng Chenggong led the army to recover Taiwan Province, and specially handed over the Xiamen base camp to Zheng Jinglai to stay. Before leaving, in order to better stabilize the situation in Xiamen University, Zheng Chenggong personally arranged for Zheng Jing to marry Tang Xianyue, the granddaughter of Tang Xianyue, a former Ministry of War of the Ming Dynasty and an old party member in Lindong.
Unfortunately, Zheng Jing doesn't like Down syndrome very much, and their married life is not harmonious. Later, Zheng Jing fell in love with Chen Zhaoniang, the wet nurse of the fourth brother, and they also gave birth to a son, Zheng Kecang.
At that time, Chen Zhaoniang had a husband, so his behavior in Zheng Jing was very immoral. More importantly, Chen Zhaoniang is Zheng Jing's younger brother's wet nurse. You know, in ancient society, the wet nurse was equivalent to half a mother, even her own brother's wet nurse was equivalent to half a mother, which means that Zheng Jing and Chen Zhaoniang's adultery was completely against the world.
What is even more frightening is that Zheng Jing and Chen Zhaoniang gave birth to a son. If this matter gets out, not only will the whole Zheng family lose face, but it may even completely ruin the anti-Qing cause. For similar reasons, when Chen Zhaoniang gave birth to Zheng Kecang, when Zheng Jing reported to Zheng Chenggong, she only dared to say that she was her own son and a concubine.
Zheng Chenggong didn't know the real situation, so he was very happy to have a grandson, so he specially sent someone from Taiwan Province to reward Zheng Jing. Zheng Chenggong's behavior directly angered Zheng Jing's original wife, Tang Xianyue, so he personally wrote to Zheng Chenggong and told the whole truth.
Soon, the news that Zheng Jing was having an affair with the wet nurse and gave birth to a son spread quickly on the island of Taiwan Province Province. The Confucian scholar-officials in Taiwan Province Province agreed that this was an enemy to the world and a challenge to Confucian orthodoxy. They unanimously demanded that Zheng Chenggong give everyone an explanation, otherwise the etiquette would be chaotic and the country would split.
At the same time, Zheng Jing's legal inheritance right has also been questioned by everyone. Taiwan Province scholar-bureaucrat group and some military and political leaders agreed that Zheng Jing had seriously violated Confucian orthodoxy and was no longer qualified to be a prince. They unanimously demanded the replacement of the candidate for the prince. In this context, the Zheng Group quickly split into two camps, and the relationship between the two sides began to be tense.
As the saying goes, it rains all the time. At this moment that worried Zheng Chenggong, the Qing court ordered the execution of Zheng Chenglong, Zheng Chenggong's father, and sent people to dig Zheng Chenggong's ancestral grave. Everyone in these columns directly made Zheng Chenggong vulnerable.
Seeing that his time was running out, his own group went from bad to worse because of Zheng Jing's problems. Zheng Chenggong had to get rid of the scourge of Zheng Jing very reluctantly, so as to avoid the military and political bosses in the group fighting for the heir after his death, which eventually led to internal division and was carved up by the Qing court.
For the same reason, Zheng Chenggong ordered the killing of Zheng Jing (eldest son), Chen Zhaoniang, Zheng Kecang (grandson) and Zheng Jing's mother Dong Yougu. However, it backfired. Zheng Tai, who was in charge of executing orders at that time, had a good relationship with Zheng Jing. Based on Zheng Tai's interests, he wants Zheng Jing to take the upper position, so his rights and status must be upgraded.
On the contrary, if Zheng Jing is killed, it is difficult for Zheng Tai to have much room for future development. So when Zheng Tai received an order from Zheng Chenggong, he did not kill Zheng Jing, but staged a coup with Zheng Jing and took control of Jinmen and Xiamen.
When the news came back to Taiwan Province Province, Zheng Chenggong vomited blood on the spot and died at the age of 39. Subsequently, the Taiwan Province Scholar-bureaucrat Group and the military and political leaders collectively supported the succession of Zheng, the Five Emperors of Zheng Jing, and declared Zheng Jing a traitor. Since then, the Zheng Group has officially split.
More than a month later, the Xiamen faction headed by Zheng Jing and the Taiwan Province faction headed by Zheng Gong went to war. In this process, a very important person chose to stand on Zheng Jing's side and finally helped Zheng Jing win the final victory.
This very important figure, Chen Yonghua, is the prototype of Chen Jinnan, the chief helmsman of The Duke Of Mount Deer Middle Heaven and Earth Society in Jin Yong's novel.
