Wá hā hā (娃哈哈) is a famous Chinese beverage brand name, literally meaning 'baby laughs'—a vivid, onomatopoeic expression evoking innocent, joyful laughter. Though it originated as a proper noun for the company and its products (especially children’s drinks), it has entered informal spoken Chinese as an idiomatic interjection or noun to convey pure, carefree happiness—similar to saying 'pure delight' or 'unadulterated joy' in English.

The characters break down as 娃 (wá, 'baby' or 'child') and 哈哈 (hā hā, reduplicated onomatopoeia for laughter). The repetition of 哈 reinforces lightheartedness and spontaneity. While rarely used in formal writing, it appears frequently in casual speech, social media, and advertising to evoke warmth, nostalgia, and childlike cheer—often with affectionate or playful connotations.
