新安县
From 1661 to 1669, the territory was affected by the Great Clearance, ordered by the Qing dynasty's Kangxi Emperor, which required the evacuation of the coastal areas of Guangdong. It is recorded that about 16,000 persons from Xin'an County were driven inland and 1,648 of those who left are said to have returned when the evacuation was rescinded in 1669. What is now the territory of Hong Kong became largely wasteland during the ban.
