I think it's good to join the express delivery company in Yantai.

If you join, I think it will be SF, Tong Yuan, Shentong, Zhongtong or Dayun. . . Generally, these couriers will be chosen. Taobao has many SF packages, which are very fast. The price in Tong Yuan is cheaper and slower than that in SF. The last few words are generally chosen by sellers who have just started. Personally, I still recommend SF Express and Tong Yuan, and Taobao is used more.
