It seems that you are not familiar with Dongguan at all. A town without a canal name! Dongguan Canal is an artificial river channel excavated in 1960s, with a total length of 103km, which is the longest canal in Guangdong Province. Dongguan Canal starts from Jiantangkou, Qiaotou Town, flows through 13 Town Street, and goes from Chang 'an to the Pearl River. Yanhe Road is Canal Road, which generally refers to the vicinity of Guancheng Cultural Square in the city center. Give you a link to Dongguan Canal Road and see which one you want to know. I don't know. Ask again.
