How to write on the envelope of ancient letters?

Envelopes and stationery are written vertically from right to left. The top of the right side of the envelope is pushed to the head to show respect for the recipient, and the content is the detailed address of the recipient. Write the name and address of the recipient in the middle. Finally, write the word "Chyi Chin". If the recipient is an elder, address him on the right to show respect. Write the sender's address and name as low as possible on the left to show the sender's humility.
