Dongguan is located about half way between Hong Kong and Guangzhou, 23 North Latitude, 114 East Longitude if you're going by lat/lon or about 30km south of Guangzhou on the Guang-Shen expressway if you're going by highway.

Dongguan is a city of contrasts, with modern glass and concrete buildings near small older villages, luxury European cars vying for street (and sometimes sidewalk space) with bicycles, large mansions down the street from factory dormitories, farms next to factories.
