Recently I tried many ways to get an QOJ's login, but all failed. There seems to be only one way for me(even it's illegal), I'll pay 80000000CNY for an Qingyucup div1 login and another 80000000CNY for a div2 login. I'll use it carefully(won't share it to others or participate in live contest by it), just for solving some problems.

If you know exactly what I mean and want to help me, please contact me with this email: orz@qingyu.shi

This post might be illegal in Qingyuforces too, I'm sorry for the bother.
