寶安縣
In 1953, four years after the founding of the People's Republic of China, the Bao'an County government decided to move to Shenzhen, since the town was closer to the KCR and had a larger economy than Nantou. From the 1950s to the end of the 1970s, Shenzhen and the rest of Bao'an County oversaw a huge influx of refugees trying to escape to Hong Kong from the upheavals that were occurring in mainland China, and a range from 100,000 to 560,000 refugees resided in the county.
