What happened to Zheng after Zheng Zhuanggong's death? (detailed introduction)

Zhuang Gong died in the forty-third year of his reign. Gong Li, the son, expelled the prince and became king on his own. In the twenty-eighth year of Gong Li, Zheng was in chaos, and Zheng declined gradually. Qi gradually gained the upper hand and began to control small neighboring countries. Gong Li was handed down from Miao Gong for two generations. After that, Zheng Wei threatened Jin Chu, and there was no peace every year. Miao Gong Chuan and Xiang Gong were two generations. Zheng was captured by Chu, and Xiang Gong endured humiliation and saved the country. When Xiang Gong was passed on to Gong Jian for four generations, the State of Zheng appointed Zi Chan as the Prime Minister, forged the tripod, developed the economy, helped the people, and made the State of Zheng prosperous again. When Gong Jian IV reached Aigong, Jin, North Korea, Zhao and Wei were strong and Zheng was weak. After mourning for the public, there was a public period. Han Wuzi captured the state of Zheng and killed the public. Later, Gui Gong, the younger brother of You Gong, revived the country and fought with Sanjin for many times. After Kandy's rule, South Korea became strong again. In the twenty-first year of Kang Gong (the first 375 years), Han Aihou led an army to capture Zheng again, and Zheng perished, and its territory was merged into South Korea.
