Hello Codeforces,

I am already a retired competitor, but recently the regional contest held in Qingdao is considerably controversial(sorry only Chinese).

Online board here.

Many contestants complained about things like data(solution with higher complexity got passed, while lower one got TLE) and problemset (as you see, 3 problems you may get gold, while silver and bronze at the same time). For me, though not insider, I still felt bad as well. They should have do their best on data and difficulty, as it is their responsibility.

The thing is, our contestants have no where to complain and they do not even know the exact problemsetters, really disappointed.

Have you ever had some regional contest experience? What is your attitude on this one?
