The entire Pearl River Delta area of China is a manufacturing powerhouse. Huaqiangbei, the famous giant electronics market, is just a tiny facet of a huge industrial ecosystem. About 30 minutes north of Shenzhen there’s a giant market the size of a town that supplies not just electronics, but chemicals, materials, tools, machines, and, of course, furs and leather.
South China Market is a planned development resembling a covered lumberyard spanning several square kilometers. Its frikin’ huge, but also eerily empty. They built it up, but its either not been successful or is still filling out. This street is almost exclusively ABS plastic bead vendors, with a few colorant shops interspersed.
