First of all, the sender must fill out the form clearly. Generally, there will be an option on the express delivery form to let you indicate what kind of packaging it is: a carton or a bag, etc. If you don't have this item, just write it down yourself. Another thing the sender should note is that if it is payable on delivery, the courier must weigh and rewrite the price. Generally, the courier's scale is absolutely indispensable, and the recipient can also check the goods based on the weight. If the weight is wrong, there must be something wrong, then refuse to sign for it

When the recipient receives the package, do not sign first. First check whether the packaging is consistent with the order. If it is not stated on the express delivery note, it is best to confirm with the sender in advance.

Then check whether the outer packaging is damaged, and refuse to sign for it if it is damaged
