1905年清政府廢除科舉，建設新式學堂教授西學，並陸續與各國簽訂留學政策，使中國形成一股留學風潮。胡適、郭沫若、傅斯年投身加入留學生的行列，胡適留美、郭沫若留日、傅斯年留歐，他們三人留學的國家以及留學生活都是當時中國留學生群體的縮影，他們因國家政策轉向而從傳統知識份子轉成留學生，藉由他們與親友往來的書信得以讓人一窺留學群體的生活面向。 以微觀來看，他們以當時社會風氣——實業救國，不約而同地選擇理科，後來則因個人興趣而有所轉向。在異國他鄉求學，校園的生活環境、閒暇時刻的娛樂方式、郊遊、思念遠方親友皆藉由魚雁往返傳遞情感，他們在留學國的人際往來亦可藉由書信來了解。 以宏觀來看，這三位都是以官費留學生的身分到他國留學，因此，能否按時領取官費以及官費的運用也深刻影響留學生。官費背後的運作與國家和國際政局是否穩定有關，因此，在書信中三人除了各自提到如何運用官費、官費是否寄達，其生活狀態有無影響之外，他們也多半留意中國國內政治以及國際局勢動向，由此可知，留學生與整體社會環境與政治局勢密不可分。 留學生的生活面向以及其關心的議題藉由同一時期三位留學於不同國家的留學生——胡適、郭沫若、傅斯年展開。;After the Qing government abolished the imperial examination system in 1905 and promoted Western-style education， a wave of overseas study emerged in China. Hu Shih， Guo Moruo， and Fu Ssu-nien—government-sponsored students in the United States， Japan， and Europe—embodied this broader trend. Their letters to family and friends offer a window into the daily lives of early Chinese students abroad. On a personal level， all three initially chose scientific fields in response to the era’s emphasis on strengthening the nation through practical knowledge， later shifting their interests over time. Their correspondence reveals details of campus life， leisure activities， social interactions， and emotional ties maintained through writing. On a broader level， their experiences were closely shaped by the stability of government funding， which was itself influenced by domestic politics and international conditions. Their letters show concern not only for their stipends but also for China’s political situation and global affairs， demonstrating the close link between overseas students and the wider sociopolitical environment.
