SuperBart In fact, I had previously sent the high-speed train cleaning bag via mail, and with the current postal service, as long as your information is clear and doesn't interfere with recognition or scanning, they will usually pick it up. This mainly depends on whether the salesperson is willing to accommodate you – whether to handle it privately or go to the counter to send it. If there are any problems, they will point them out to you in person. Once the counter receives it, no one will stop you, because you have already sent it. Also, sorting is usually automated, and if the delivery department returns it to you, it would be more complicated. They still prefer to continue delivering it to you.
