Which industries are in which districts?
A practical starting point for locating electronics, precision machining and CNC-related suppliers around Shenzhen and Dongguan.

Start with the product and process, then narrow the city and district. Shenzhen has major electronics and technology activity across several districts, while Dongguan's manufacturing base is spread across many towns. A city name alone is too broad for a useful day route.
For an electronics visit, ask for the actual production address, key processes done in-house, testing capability and the location of component partners. For CNC work, request process capability, materials, tolerance and inspection details before deciding which workshop to visit.
Send me the supplier addresses and product brief. I can group visits into a route and flag where travel time may make the proposed schedule impractical.
