大A大B
dà A dà B
The structure '大A大B' (big A big B)
Explanation
This is a four-character idiom form (四字格 sìzìgé) following the template 大A大B (dà A dà B): insert two verbs (or adjectives) of the same type into the A and B slots to emphasize and exaggerate an action.
大 (dà) + A + 大 (dà) + B, where A and B are two words of similar meaning or the same theme. For example 大吃大喝 (dà chī dà hē = to eat and drink to excess), 大吵大闹 (dà chǎo dà nào = to quarrel noisily).
when you want to describe an action that occurs to a strong, excessive degree, usually with a negative or critical connotation.
大 here does NOT have the literal meaning 'big'; it merely serves to exaggerate the degree; the whole phrase is a fixed block and you cannot arbitrarily change the words.
Vietnamese learners often randomly combine any two verbs into this template; in reality only certain fixed combinations work (大吃大喝, 大吵大闹, 大是大非...), so learn them as set phrases rather than making them up.
Examples
Your habit of eating and drinking to excess is bad for your health; you must change it.
She is in a bad mood and makes a huge fuss over the smallest thing.
