‘试行’ (shì xíng) is a verb meaning ‘to implement on a trial basis’ or ‘to put into temporary effect for testing’. It combines the characters 试 (shì), meaning ‘to try’ or ‘to test’, and 行 (xíng), meaning ‘to carry out’ or ‘to implement’. Together, they convey the idea of putting a policy, system, method, or rule into practice temporarily to evaluate its effectiveness before full adoption.

This term is commonly used in formal, administrative, educational, or organizational contexts — such as government announcements, school reforms, corporate procedures, or new regulations. It implies intentionality, evaluation, and potential revision: the trial period allows stakeholders to observe outcomes and make improvements. Unlike casual experimentation, ‘试行’ carries official weight and often follows careful planning. It’s frequently followed by time phrases (e.g., ‘为期三个月’), or paired with nouns like ‘办法’ (method), ‘方案’ (plan), or ‘制度’ (system).
