tham đó bỏ đăng

Definition
  1. Idiom:
    • To be fickle or opportunistic; to abandon the old for the new: This idiom describes the behavior of a person who is capricious, disloyal, or easily swayed by new temptations, leading them to discard what they previously had or valued. It implies a lack of steadfastness and a tendency toward greed for the new and novel.
    • Literal origin: The phrase originates from fishing tools. "Đó" is a stationary fish trap, and "đăng" is a movable fish weir or trap. The literal image is of a fisherman who, upon seeing a fish in the "đăng," greedily abandons the "đó" he was holding to chase the new prospect, often resulting in catching neither.
