Where are the stamps on the envelope?

According to the experience of querying Baidu, the correct way to stick stamps on envelopes is as follows:

1. If there are few stamps, or if there is a stamp, just stick it directly on the "stamp" of the envelope, which is convenient and quick.

2. If the letter is big or heavy, you need to paste several pieces. If you can't paste it at the paste place, you can paste one at the "paste place" and several at the lower left ticket.

It is ok to stick it on the back, but it must be on one side. If it's in the front, it's stuck in the front, if it's in the back, it's stuck in the back.

4. Use postal stamps. The stamp has been affixed, so you can put it directly in the letter without affixing the stamp. If you don't seal it, you can put it directly. If you are afraid of losing it, you can seal it.

Stamp, a Postagestamp certificate for mailing, is generally issued by sovereign countries. The square space of stamps often reflects the history, science and technology, economy, culture, customs and natural features of a country or region, which makes stamps have collection value in addition to postal value.
