Ok I made a mistake, after I answered I discovered that you are Japanese, I don't understand how google can confuse Japanese with chinese, but if I put this word in Google translator and I switch from chinese to japanese it says "big chill", It's really strange! I'm sorry bye

I'm not English and I do not know chinese, but if you put "大寒波" on Google translator you get "big Hanbo" and I found out on the internet that it is a stick for fighting some martial art like that in this video https://www.youtube.com/watch?v=Ltkjqs5jhKc, I hope that is useful for you. Bye

i haven't heard the"大寒波"ever.what is this?Is it a card game?
