How to prevent real estate from being impersonated when it is distributed to owners?

Express label, similar package weight, reminding to handle with care, etc.

1, express labeling: paste the express instructions from home that say "a pair of book cities".

2, the packaging weight is similar: the weight of the mobile phone is similar to that of the book town.

3. Remind to handle it with care: Book City is fragile, so you can remind the recipient to handle it with care.
