After Colonel Hsieh's retreat to Shanghai at the end of October and the bloody battle of the 800 heroes, Wei Sheng, moved by their sacrifice, wrote a patriotic song which lifted the spirits of the people of Shanghai.
魏笙雖不樂意，仍勉強接受。十月底，國軍撤退，四行倉庫中八百壯士浴血拚鬥。魏笙鬱悶之心，發而為曲，寫下這首「中國不會亡」，不顧金豔伶反對，設法在上海天音小組的地下廣播電台播放，上海市民聞歌鼓舞。
