醉生梦死醉死梦生zuì shēng mèng sǐ

lead a befuddled (/happy-go-lucky)life; live as if in toxicated (/drunk)or dreaming
❍ 唔？ 真是～！ (李六如《六十年的变迁》Ⅰ—85) Oh,what a befuddled idiot!/不过洋书是应该读的，读了洋书，书里知识就多些，不会～当亡国奴。(李六如 《六十年的变迁》Ⅰ—84)However,foreign books are entirely different; they should be read. If we study these books we’ll know more about the real world and not live in a dream world until one day we wake up and discover we have become slaves in our own country.
