瞧瞧(qiáo qiáo) - have a look, take a look in Mandarin

瞧瞧 (qiáo qiáo) is the doubled form of 瞧, and the doubling is what softens it. A repeated verb in Mandarin makes the action brief and casual, so 瞧瞧 means "have a quick look" rather than "look at". Compare 看 with 看看: exactly the same trick.

瞧 is more colloquial and more northern than 看. It is spoken language, common in Beijing and in dialogue, rarer in writing. If you are unsure which to use, 看看 is neutral everywhere; 瞧瞧 makes you sound relaxed and chatty.

Used on its own at the start of a sentence, 瞧瞧 becomes an attention-grabber close to English "look at that" or "see?", often with a hint of I-told-you-so.
