‘考察’ (kǎo chá) is a formal verb meaning ‘to investigate’, ‘to conduct a field study’, or ‘to inspect on-site’. It combines two characters: 考 (kǎo), meaning ‘to examine’ or ‘to test’, and 察 (chá), meaning ‘to observe carefully’ or ‘to survey’. Together, they emphasize thorough, firsthand observation—often involving travel to a location to gather information, assess conditions, or evaluate feasibility. Unlike casual observation, 考察 implies purpose, method, and professional or academic intent.

This word is commonly used in contexts such as scientific research, urban planning, environmental studies, education, and business development. It frequently appears in official reports, news articles, and academic writing. While it can be used transitively (e.g., 考察一个地区), it’s also often followed by prepositions like ‘到’ (e.g., 考察到云南) or ‘后’ (e.g., 考察后决定). It is not used for everyday curiosity—it carries weight and intentionality.
