где флаг РФ ?

They're speaking in Russian. It's actually a really easy language, you should try learning it sometime.
I'm pretty sure OP is asking where the Russian flag went.
Gde = where is, flag = flag, 'RF' = I don't know, I am assuming Russian?
The rest is spotty for me, but I believe Ivan is repeating the question and AvTori is answering it.
Usin da goggle is probably better than any translation I can give you, though.

You can learn Cyrillic in an hour, but you can learn the Chinese alphabet in... Hell, does anybody know the whole Chinese alphabet?

I've studied enough Russian to know that any difficulties or intricacies the language may have pales in comparison to the difficulty of having to know thousands of different characters and a different grammar structure from English. Russian seems to have a pretty similar structure to English.

matters what "Chinese". Mandarin???

The flag was removed because of the war in Ukraine, and why are ordinary chess players from Russia to blame?
It is not to blame ordinary people. But It is (among other reasons) to motivate them to stand agains government who attacks and kill thousands of ordinary people in Ukraine.
Sometimes it is just to let people of Russia know that there is a regular war in Ukraine, that Russian is an aggressor and that the world is not accepting that. It is hard to believe, but propaganda is Russia is very strong and some Russians simply are not aware of the truth.

Yet it isn’t my flag which is wiped out. I guess according to your logic all the world is brainwashed but you. Live in your propaganda bubble if you want, nobody sensible is buying that anyways.

I have no time to read all this Russian trolls rage, but I actually pity all those Russian trolls. It must drive them crazy knowing all the civilized world is against Russian aggression, so much that Russians cannot even play under own flag in most recognized sports. What’s more Russia must bow now to China and North Korea. So humiliating… and all this because of sick ambitions of Putin.
