When can I send a letter to China Antarctic Post Office?

China Antarctic Great Wall Scientific Research Station does have a post office, Antarctica.

Most of them are sent back to China as souvenirs when traveling.

For sending a letter to the post office of the Great Wall Station, you can send it in an envelope (greeting cards and postcards are put inside).

In the greeting letter, you can express your hope that the post office can send the postcard in the envelope back to China.

(You need to put enough stamps on the postcards yourself), but this is not a compulsory or compulsory service business.

So it depends on your personal lucky value.
