'Migrant city' of Dongguan most empty during festival

Dongguan, one of the major production centers in Guangdong province, was ranked the emptiest city on the mainland during the Spring Festival holidays, which ended on Thursday.

Nearly 70 percent of the city's residents left Dongguan - known as a migrant city - to spend the Lunar New Year with family members, according to 360 Big Data Center.

Located in the middle of the prosperous Pearl River Delta, Dongguan joined three other Guangdong metropolises in the top five.
