A return that is too late on the other hand may be cause for regret. Maybe you want to return in order to lecture, to invest, or to stand for election. But wait too long and the opportunity is lost--the classes have finished, the factory is built, or the elections are over.
返鄉如果太晚，也會造成遺憾，因此無論要講學、要投資、要競選，都要擇時機行事，否則如果等到演講的學都講完了；該設的廠都設滿了；各縣市鄉鎮都改選得差不多，返鄉的最佳時機也就過去了。
