How would one accurately translate "万事大吉"? This is a four character phrase for which I have found no accurate translation online. I hear it all the time around CNY. 


  万事大吉
This is an expression wishing the listener good luck. Any equivalent English expression will do: "Best of luck in all your endeavors", "May your every endeavor prosper", etc. The use of the character 万 (wàn, meaning "10,000"), here just means "many" or "all".
