Another personal suggestion:
Send your own things, don't use Tong Yuan. Even if you go to Taobao to buy things, you should ask whether the seller is from Tong Yuan. If the seller sends it to Tong Yuan, ask if you can change the courier company. There is really no choice but to pick up the Tong Yuan Express.
I'm not slandering Tong Yuan, but my personal Taobao buyer's credit has also been exploited. I bought almost 300 things in Taobao. I really learned a lot about the service, attitude and speed of the courier company. Tong Yuan really can't accept it.
