About ryanyang...
"Hi,
My name is Ryan and I am 19 years old. I live in China and study in Hong Kong and I am excited about the postcard related to the countries or cities from all over the world.
I hope to receive the post card that have some pictures of the beautiful scenery, buildings or other places that can represent your country or your city:-).
In addition, if you can write some words in your own language, it will be wonderful:-).
At last but not least, I hope you can write a sentence: Postcard from XX(your country name) or any words that can indicate where the postcard from:-).
PS: please don't use envelop, because I think postmark is very meaningful.
Thanks for your reading and happy everyday!"
