The mailing time of post office brush products can be delivered in about 10 days, which varies greatly from region to region.
Post office hanging brush products are delivered in the same way as letters and newspapers. Small registered printed matter is sent directly to the receiving address by the post office courier, but if it needs to be signed, a notice will be sent to the designated post office for collection.
After 30 days from the date of mailing, the post office can handle the inquiry, and the longest validity period is within one year from the date of transaction.
Printed matter refers to books, newspapers, periodicals, teaching materials and book catalogues printed by using the unified standard book number, certificate number or Chinese standard book number approved by the publishing administrative organ at or above the provincial level, and can be delivered as printed matter.
