Why are all the things cdf bought delivered in Shantou?

Generally, there are many wholesale places and factories in Dongguan, Shenzhen.

It is possible that the source of goods comes from Guangdong.

See what brand and product it is. For example, Acer laptop, the factory is in Shanghai.

But if it is a mobile phone, many of them are here in Shenzhen. I suggest you consult customer service.
