It is the unforeseen that always happens. 天有不測風雲，人有旦夕禍福。

It is the first step that costs troublesome. 萬事開頭難。

It is no use crying over spilt milk. 覆水難收。

It is never too old to learn. 活到老，學到老。

It is hard to please all. 眾口難調。

It is easy to open a shop but hard to keep it always open. 創業容易守業難。

It is easy to be wise after the event. 事後諸葛亮好當。

It is easier to get money than to keep it. 掙錢容易攢錢難。

It is better to die when life is a disgrace. 寧為玉碎，不為瓦全。

Industry is the parent of success. 勤奮是成功之母。
