Hello, codeforces!
Recently I had a problem: Are there any foreign programming websites which can be accessed in China? Why do I have this problem? Because I started learning programming just a half year ago, and I know few about foreign programming websites(except codeforces).
So, if you know any about foreign programming websites, please make comments under this blog,thank you very much!

Can I use vjudge?
Atcoder.
Ok. Thanks.
I like Project Euler.
Also, DMOJ works. onlinejudge.org also works but is slow. poj.org is run in Beijing but is mainly English.
