Cách sử dụng
"Not to be sniffed at" means something is important or significant, even though it might not seem like it at first. For example, if someone offers you a job with a lower salary than you wanted, but it's a great company with lots of benefits, it's not to be sniffed at. It's something you should consider seriously. This phrase is often used to talk positively about something that may seem small, but actually has value.
