The history of Dongguan can be traced back to the Neolithic Age. In Xia Dynasty, Dongguan belonged to the southern region. During the Spring and Autumn Period and the Warring States Period, Dongguan was the land of Baiyue. 2 14 years ago, Qin Shihuang merged with Lingnan, and Dongguan belonged to Panyu County, Nanhai County. In the Eastern Han Dynasty, Shun Di set up Zengcheng County in Panyu, and Dongguan was subordinate to Zengcheng at that time. In the sixth year of Xianhe in the Eastern Jin Dynasty (AD 33 1 year), Li County, Dongguan, was originally named Baoan. In the second year of Tang Zhide (AD 757), it was renamed Dongguan, and the county seat was located in Yong (now Guancheng Street). According to legend, Dongguan is named because it is located in the east of Guangzhou (now southeast) and is rich in aquatic plants (grass). In Qing Dynasty, Lin Zexu destroyed opium in Humen. During the period of War of Resistance against Japanese Aggression, Dongguan was one of the anti-Japanese bases of Dongjiang Column.

(Four Little Dragons in Guangdong1Four small and medium-sized cities in the Pearl River Delta of Guangdong, which developed rapidly in the 1980s-Nanhai, Shunde, Dongguan and Zhongshan, are the signs that Guangdong took the lead in reform and opening up. In 2005, the per capita GDP of the "Four Little Dragons" has approached or reached the internationally recognized "development threshold" of 5,000 to 9,000 US dollars.
