Hi, my name is Yan Yin! I'm 28 and work in a pharmaceutical company. I love choosing postcards to send to people, and also receiving postcards from around the world.
Here are some of the things and postcards I love:
Hank and John Green, and Nerdfighteria (DFTBA!)
Pride and Prejudice (and Colin Firth)
Musicals (Les Mis, Phantom, The Greatest Showman...)
Books (especially classics)
Movies (The King's Speech, Star Trek, Indiana Jones, X-Men, MCU...)
TV shows (Sherlock, The Crown, Masterchef Australia, Whose Line)
The Adventures of Tintin
Cards showing your local food
Leonid Afremov's work
Famous paintings (especially by van Gogh)
Quirky/ vintage/ minimalist/ unique postcards in general
Also, I'd be overjoyed if you have something from my favourites list- it has a mix of postcards that I'd love to have, and postcards that I already have and love. Or just send a postcard that you like and tell me why! I'm not a fan of cards with the typical tourist landscape views though, and try to avoid advertisement cards too unless if they're related to the list above.
If you need inspiration for what to write, here are some ideas:
Something about yourself/ your country
What you did during your day
Interests that we share (from the list above)
Favourite/ last book you read
Favourite/ last movie you watched
Something that makes you happy
Something on your bucket list
The messages are appreciated just as much as the postcard.
