Will I receive the pick-up code after unloading the rookie package? Do I have to download the rookie wrap to send the mail to the rookie station?

If there is, the courier will send you a text message or call you to pick it up, or see if the official WeChat account can pay attention to the delivery. Generally, you can contact directly by phone with the express number, and now you can also make an appointment with WeChat. You go to the express delivery point, and people will let you scan the code and fill it online.
