About Neutrino...
I am a senior student from Guangzhou , Guangdong ,China
I like all kinds of postcards.
But I like these kinds best:
maps
some famous places/people/buildings/scenery
science (such as physics,chemistry,astronomy,biology,psychology,geography)
history
about nature
stars and sky
all plants and animals
national flag
handmade card
black and white
classical music
But it's still alright to receive all kinds of postcards.
And please write a little bit more than "happy postcrossing" on your card. Maybe an aphorism in your language with translation,;what you going to do tonight; a book, film or music recommendation; your favorite dish...
