It is not enough to write only English letters. If you want to send a letter smoothly, you must learn how to write an envelope.

First, write the writer's name and address in the upper left corner or back of the envelope. The address should be from small to uppercase, which is exactly the opposite of Chinese address. For example:

Su Yang (Su Yang)

Block 503 (block 503)

Haimen Jiefang West Road (Haimen Jiefang West Road)

Jiangsu 226 100

China (China)

Then, write the name and address of the recipient in the lower right corner of the envelope. For example:

Mr david green.

English Department (English Department)

Columbia University (Columbia University)

New york 10027 (new york)

Unit United States (United States)

Stamps are usually affixed to the upper right corner of envelopes.
