Zheng Chenggong’s family is not extinct, and there are still descendants. Where did the original poster see that his descendants were cut off? Although the Qing Dynasty repeatedly persecuted the Zheng family after Zheng Keshuang surrendered to the Qing Dynasty. In the end, the family gradually declined due to poverty, but it did not mean that the descendants were cut off.

Zheng Shourang (formerly known as Zheng Mingneng), a well-known ichthyologist in Taiwan, is the ninth grandson of Zheng Chenggong (descendant of Zheng Chenggong’s sixth son, Zheng Kuan). The poet Zheng Chouyu (original name Zheng Wentao) is the grandson of Zheng Chenggong.

When Zheng Chenggong's grandson Zheng Keshuang was dying, he wrote in a memorial that "the family was poor and it was difficult to raise a child" and asked for an assistant collar. After the memorial was approved, it was managed twice by his seventh brother Zheng Keshuang and his son Zheng Ande. , after which the two assistants were merged into one. After Zheng Keshuang's death, his three sons, Anfu, Anlu, and Ankang, continued to be under house arrest. Their lives were in dire straits, and the court's salary was still insufficient to sustain their livelihood. His mother, Huang, once again requested the Qing government to return the Zheng family's property. Although an inventory was ordered, nothing happened. After that, some jesters in the Qing court provoked various troubles and persecuted Zheng Keshuang's children and grandchildren. The Zheng family was often blamed in Beijing. Due to trivial matters, Keshuang's son Zheng Anfu was dismissed from his post, and his younger brother Zheng Keshu was demoted or exiled. In the border areas, they were either demoted to slaves or killed... By the sixth year of Yongzheng (1728), only half of the subordinates were left. In the ninth year of Yongzheng (1731), the Ministry of Internal Affairs allocated a strong man to add an assistant. Zheng Keshuang's son and son led Zheng Ankang to manage it. In the tenth year of Yongzheng (1732) and the 22nd year of Kangxi (1683), Liu Guoxuan was established as assistant. Collar merger. This branch of the Zheng family slowly disappeared from the stage of history as their family property was exhausted and their descendants gradually declined.
