Shenzhen Bao'an International Airport
Bao'an was reverted into county status in 1981, as the administrative unit of the area that belongs to Shenzhen, but now belongs to Shenzhen Special Economic Zone. Border patrols were also established in the border of the Economic Zone. In 1991, Shenzhen Bao'an International Airport, located in Bao'an County, was opened.
