背道而驰 to run counter
走汤蹈火 to go through fire and water
风烛残年 to have one foot in the grave
风声鹤唳，草木皆兵 to apprehend danger in every sound
活到老学到老 It's never too late to learn./ Live and learn.
前事不忘后事之师 Remember the past and it will guide your future.
星星之火可以燎原 A single spark can start a prairie fire.
待人宽容如待己 Live and let live.
按部就班 Learn to walk before you run.
