There is no smoke without fire. 　　无风不起浪

Although the sun shine, leave not your cloak at home. 未雨绸缪

A snow year, a rich year. 瑞雪兆丰年

A year's plan starts with spring.一年之计在于春

Fortune knocks once at least at every man's gate.风水轮流转

It is the unforeseen that always happens.天有不测风云，人有旦夕祸福

Nature is the true law.天行有常，不为尧存，不为桀亡。

Rome is not built in a day. 冰冻三尺，非一日之寒

Evening red and morning grey are the sign of a fine day. 晚霞行千里

He sits no sure that sits too high. 高处不胜寒
