秀才不出门，能知天下事

without going outdoors, a scholar knows all the world's affairs

that scholars understand what is happening outside while staying at home

秀才 refers to accredited scholars in ancient China. In the past, this phrase means that scholars understand what is happening outside while staying at home.

秀才，读书人。

秀才不出门，能知天下事，旧时指读书人即使待在家里，也能知道外面发生的事情。现在指不必亲自到达现场，通过间接的渠道（书本、报纸、电视或因特网）也可以知道世界上发生的事情。
