My mother sent clothes from Guangdong to Beijing by express delivery. What time does it arrive? Will it be returned if you don't pick it up a few days after arrival?

Usually, I buy things in Taobao, and the sellers use logistics companies to send express delivery, which usually takes 3-5 days to arrive. Postal service has never been used, it's hard to say ~ In addition, the logistics company always calls me, then determines the address and time, and then delivers it to the door. Postal service should be the same, otherwise there is no one at home, and delivery is free ~ If the consignee cannot be contacted, or the address and consignee have problems, the logistics company will deliver it directly to the door.
