千万 (qiānwàn) might look like it’s talking about numbers ("a thousand ten thousand" maybe?), but it actually means "to make sure" or "absolutely." You’ll often see it used in the negative, but it works in the positive, too. It really gives your sentence a bit of extra oomph!
Typically, 千万 comes at the beginning of a command and is often paired with words like 要, 不能, or 别. You can use 千万 to strongly tell someone either to do something or not to do something—depending on the situation!
Sample Sentences
千万不要忘记带钥匙！Make sure you don’t forget to bring your keys!

这次机会很好，千万不要错过！This is a great opportunity, make sure you don’t miss it!
