'Chèn zǎo' literally combines 'chèn' (to take advantage of, to seize an opportunity) and 'zǎo' (early), forming an adverb meaning 'as soon as possible' or 'while it's still early' — emphasizing timely action before conditions worsen or chances disappear. It conveys urgency without panic, suggesting prudence and foresight: you act now because the moment is favorable.

This phrase is commonly used in practical, everyday situations — advising someone to leave before traffic builds up, submit documents before a deadline, or address a small problem before it escalates. It often appears with verbs like '去' (go), '办' (handle), '说' (say), or '解决' (resolve), and typically precedes the verb it modifies. While it implies 'early' chronologically, its core nuance is strategic timing — not just calendar time, but recognizing a window of opportunity that won’t last.
