Consequently (于是)
于是
于是 (yúshì) means "consequently," "thereupon," or "so" and connects a cause or situation with its natural result or next action, often used in narrative contexts.
Pattern
Situation/Cause，于是 + Result/Next Action
Explanation
于是 is a conjunction that indicates a natural consequence or next step following a situation. It is more literary and narrative than 所以 and is commonly used in storytelling, descriptions of sequential events, and written Chinese. While 所以 emphasizes logical causation ("therefore"), 于是 emphasizes temporal sequence and natural progression ("and so/thereupon").
于是 typically appears between two clauses or sentences, connecting a situation to the action that naturally followed. It implies that the action was a natural or expected response to the preceding situation, not just a logical deduction.
Key difference from 所以: 所以 pairs with 因为 and states a logical reason-result relationship. 于是 describes what happened next as a natural response — it is more about narrative flow than logical deduction.

Common Mistakes
Wrong
于是天气冷了，他穿上了大衣。
Correct
天气冷了，于是他穿上了大衣。
于是 introduces the result/consequence, not the cause. It must come before the resulting action, not before the cause.
Wrong
因为下雨了，于是我带了伞。
Correct
下雨了，于是我带了伞。
Do not combine 因为 with 于是. Use 因为...所以 or just 于是 alone.
