1. Incorrect delivery: the courier sent the wrong goods, resulting in the receipt of inexplicable packages. You can check the recipient information on the package to confirm whether the package has been sent to you, not yourself, and contact the courier company to negotiate the correct handling method.

2. Misleading and fraud: pranks, fraud and other illegal activities can also lead to the receipt of inexplicable packages. If you suspect that the parcel is illegal, you can contact the courier company and report it to the legal institution.
