chongyun's burst and skill doesn't do any damage. like there are no numbers when i use it

They definitely work and do damage

Without any further info about your situation, my best guess would be you just lost connection to the server or were not hitting something that was able to take damage

If for some reason you don't want to take my word on it here is a small clip showing as much, as well

alright

I restarted my game and it works now, thanks
