Hi, any Chinese here? I am curious about Chinese OI problems English Version(like Chinese NOI or something like that). Where can I find them?

Any link or resource is appreciated.

UPD: Thanks MegaOwIer for his translation NOI2019

I am not Chinese, but I know that on the most problems google translate works well (not very well, but at least I am able to read the statements)

You can find some in PEG Judge. (Though the problems are pretty old)

Do you still need it? We can send you PDF, if you need the translate of one problem, I can try to give you a brief.

    But Chinese problems now tend to be too long to understand.

    For example, [NOI2014]Zoo [NOI2016]A Great Calculation in the Fields, and nearly all problems from Ynoi.

      But if you don't care about the pictures in Ynoi.

      They are short.

        But pictures are the core of Ynoi for people who can't solve them!

    Thanks a lot! But I just want to take a glance at how Chinese problems look like. Are they difficult or do they have some special/fun points?

      Compared to the European and American problems, Chinese problems may be harder(I think at least not easier). Because these questions are generally not purely intellectual problems, you need to learn some Large algorithm. For example, as a problem with 998244353, it may need you to learned Lagrangian Interpolation, FFT to implementate code, and as a problem with string, it may need you to use SAM + SegTree/TreeSplit, and so on. At all I think Chinese problems very investigating intellect and code implementation. (Mainly probably China's FFT problems was quite a lot)

There's another series of problems in China called NOIp(NOI in provinces).The problems are easier and it's the the first round of contests in one session.

      Side note, most problems from BZOJ requires payment. (About $$$100$$$ dollars per year, increasing rapidly).

        Side note, be patient while using BZOJ. That thing is extremely slow and unstable.

          I think it's OK.At least faster than SPOJ or something.And its problems are amazing.

            yeah, SPOJ is totally unbearable.

            and I have to admit BZOJ's problems (and discusses) are amazing.

        But, we have to say, a great number of the private problems can be found in other OJs.
