About Zhang...
I'm 24 years old now. I live in the city of Nanjing near Shanghai in China. I'm a postgraduate student majoring in computer science. But my bachelor's degree is mechanics. Even though, I have no interests in mechanics. I have been a designer for electric power tools for 2 years. Then I quitted my job and took the postgraduate entrance examination and selected computer science as my new major.
Postcards on any theme will be ok. Some will be great welcomed as following:
Natural scenery about your own country, especially iceberg, glacier, mountain, river, grasslands and so on
Landscape
Universe, especially galaxies, aurora
Animals
Something about environmental protection
If you are interested in directly swapping postcards as me, just send to me.
Happy postcrossing :)
