Use 因为 (because) to introduce a cause, followed by a result or consequence in the second clause. It is a very common way to explain reasons.

The structure “..., 便...” shows that once the first action or situation happens, the result or consequence described after 便 follows immediately.

“从…到…” expresses a range or span in time, space, or sequence, similar to English “from ... to ...”.

“直至” emphasizes that something continued all the way until a specific point in time or situation. It often follows a duration expression.

“于是” is used to introduce a natural consequence or follow-up action after the situation described before it – similar to “so” or “thereupon.”
