Is it true about Mom's post office?

The mother station is a branch of Tong Yuan. Tong Yuan's home station is similar to a rookie station. It's a place to pick up goods and send express mail. If you receive the piece code of the parent station, it is true. Don't call back, don't call back, follow the address on the pick-up code and arrive at the pick-up point. Pick up the code in the newspaper and they will send it to you by express.
