hello everyone, I'm a chinese student who is one of the gold medalists in our Chinese Chemistry Olympiad(CChO), as well as the future participant of the 48th icho which will held in Pakistan. The chemistry exams in our country are far more difficult than any other ones. :(
Which country do you come from? I want to make friends with you.
Here is one of the questions of the 2015 Chinese Chemstry Olympiad (Final). I translated it in English. Can you crack it? ;D

Its called Reissert compounds for the first part.

你真厉害！You are so clever. btw, which country do you come from? Are you from German? :P

是的，我是德国人

Congratulates, you are right. Do you think that these problem is difficult?
-
Yeah, I would like to see more of these. How do you compare IChO, Mendeleev Olympiad and your National Olympiad by difficulty?

Hello zhangtianzong, I was just curious to know whether China is definitely going to take part in IChO, because some major countries have already withdrawn from this year's IChO and it is still questionable if the olympiad is going to take place due to the concerns about the safety of the participants
-
Which countries have withdrawn?
-
UK, USA, Australia, India as far as I know. I believe there are some more of them
-
That should mean that they will have two years to observe before participating again, but I don't think it will happen.

Hello! I am a participant of IChO 2015 and probably will participate in IChO 2016. Have you got a facebook or twitter or smth like that to contact you? I hadn't got enough time to talk with Chinese participants on the last olympiad but I made photo with them)

Hi, Rutherford! Sorry for my late reply... (It's really strange that I'm frequently banned from using this forum..)
Generally speaking, IChO problems are the easiest among the three. However, the 45th,46th&47th problems are rather difficult, especially the 46th (which was held in Vietnam)! Moreover,the organic problems of the 46th preparatory problems are NO LESS difficult than any other organic problems which I've met.
In my opinion, Mendeleev tasks and our Chinese Olympiad possess the same difficulty. These two tasks have different emphasis and understanding in the chemistry Olympiad. Mendeleev tasks (more broadly the Russian problems) are more deductive (Which i mean is to "deduce or infer A,B,X..." ). However,Chinese tasks are more profound ,which require a broad knowledge and a solid foundation. Chinese students are required to recite 300 named reactions and many more other knowledge like this. We are also require a lot of mechanisms (Such as Grossman "the art of writing reasonable mechanisms in orgchem"!!!!)
However, Chinese tasks do not require spectroscopy and biochemistry. But we have very very very very difficult crystal problems!!!!!
Some other Chinese tasks i'll translate it later.
By the way,which country do you come from? i'm looking forward to your reply.

Hello my friend! 2016-icho will be held in Tbilisi,Georgia, not in Pakistan. I'm sure China will attend this olympiad!

Hello, ArcHos! Is it allowed to post my personal details here? Maybe we can chat in the messages.

It is possible to sent messages -search profile or member list.

I would also rank IChO as easier compared to Mendeleev. I'm sadly too old for IChO now, but I always like to do some brain teasers. I am really curious what you are learning at university in China if you must know all that for high school competition. Good that the host changed, now it's safer for the students. Wish you the first place.
