Which courier company is more cost-effective when Shanghai consigns luggage back to Chengdu? It is best to have contact information by phone! ! Thank you.
over 5kg, use ZJS, and under 5kg, use Shentong or Yuantong. Don't listen to people talk about which is good or not. All domestic express delivery is immature, so these are good. Of course, the best is SF. But the price is also a little more expensive. Generally, you don't need to call Baidu for more than 1 kilograms (unless you have valuables)' because the receiving phone number is different in every place.
