The title means 'written on the spur of the moment on coming home'. The first poem:
少小离家老大回，
乡音无改鬓毛衰。
儿童相见不相识，
笑问客从何处来。 'I left home young and came back old; my accent is the same, but my hair has thinned. The children see me and do not know me; laughing, they ask where the guest has come from.' He had been away for some fifty years.
