Shenzhen Special Economic Zone: Shenzhen is located in the south of Guangdong, on the east bank of the Pearl River Estuary, separated from Hong Kong by water, bordering Daya Bay and Mirs Bay in the east, Pearl River Estuary and Lingdingyang in the west, connecting Hong Kong with Shenzhen River in the south and Dongguan and Huizhou in the north. There are 9 administrative districts in the city, 1 new district, with a total area of 1997.47 square kilometers.

Ma Hua Teng recalled that when he first came to Shenzhen, the slogan "Time is money, efficiency is life" deeply shocked his heart. "This is a bold idea, which is unlikely to be heard in those days, just like a flash of lightning at night and a thunder in spring. Time waits for no one, and Shenzhen has since become a hot spot for national entrepreneurship. "

The core is to let enterprises get rid of administrative intervention, give full play to their autonomy, act according to market laws and economic laws, and manage and invigorate the economy by economic means.
