Generally, you only need to fill in the domestic mailing address in the province, but if it is an external mailing address, you must add the country name.

However, if it is a foreign-oriented mailing address, it is necessary to add the name of the country, and the English address is generally written in the opposite way to the Chinese description.

The order of address filling can be written from a small geographical range to a large geographical range.

Mailing address refers to the effective actual address where information can be indicated and received on envelopes, mails, e-mail boxes and other mails sent by postal means or the Internet.

In other words, no matter how to fill in the mailing address, as long as the parties can be contacted in the end, there is actually no problem.
