Commonly used in contexts involving public spaces, driving, or photography.
This phrase is frequently used in public transportation (e.g., buses, trains), driving, photography, and event venues where visibility is important.
Always use '妨碍视线' literally to describe physical obstructions. Do not use it metaphorically (e.g., for emotional or abstract 'blocking').
The phrase combines '妨碍' (fáng'ài, meaning 'to hinder/obstruct') and '视线' (shìxiàn, meaning 'line of sight/view'). Both terms are native Chinese words with roots in classical Chinese.
This phrase is literal and does not carry idiomatic meaning. It is often used in warnings or instructions to ensure visibility in shared spaces.
