For parcels, check the outer packaging carefully when receiving it to see if there are signs of disassembly, contamination, etc. According to the "Express Service Standards", the courier company is obliged to let the recipient open the box and inspect the goods before signing. If some courier companies do not implement this standard, they can choose to refuse to sign for receipt; if the item is urgently needed and the courier company refuses to accept the unpacking inspection, it can indicate "the contents of the unopened inspection goods" on the waybill. For e-commerce "online shopping" products, you can agree with the seller the terms of unpacking and inspection and require the seller to write on the waybill. If there is a shortage or damage after unpacking and inspection, you can return it or ask the courier salesperson to write a written proof, take a photo, and immediately call the merchant or the customer service staff of the courier company (remember the name of the customer service staff and the courier salesperson Or number).
