Where are many factories in Foshan, Dongguan?

The area with the largest number of factories used to be Dongguan, which was once called the world factory. I don't know if it's called Dongguan now. Dongguan has electronics factory, shoe factory, clothing factory, hardware factory, mold factory, plastic factory, knitting factory, food factory, wire and cable factory, computer software and hardware factory, etc. There are many well-known large enterprises. Every township and city has various enterprise factories, and every place has well-known enterprises. Of course, some of them have moved out of Dongguan now!
