In the Western Han Dynasty, it was renamed by the emperor because of its repeated military exploits, and it has a history of more than 2,000 years. Regarding the origin of Ding Shi, the Qing Dynasty's Jieyang County Records recorded: "Shi Ding, a native of Qin, was an official in South Vietnam and was an order of Jieyang. In the sixth year of Ding Yuan, Han soldiers went to Panyu, which belonged to Han, the emperor of Wujia, and was the Hou of Fengan Road, with 600 households in the city. At that time, the son attacked Hou, and the descendants were in Jieyang, and their reputation was abroad. "Why did Shi Ding take Jie as his surname? This leads to a historical story that Emperor Pingnan gave his surname Jieyang more than 2000 years ago. In 135 BC, Wang Ying, the king of Fujian and Vietnam, sent troops to attack South Vietnam, and Emperor Wudi sent Wang Hui and Shi Dingxing to quell the chaos, then leveled South Vietnam, and East Vietnam returned to Han. Shi Dingping made great contributions in the chaos, and was named an Daohou by Liang Wudi in BC 1 1. He took Jieyi, where he worked, as his surname, and gave his surname "Jie", which was renamed Meng. This is the origin of Jieshi.
