既往不咎 let the dead bury the dead
兼听则明 hear all parties
狡兔三窟 it is a poor mouse that has only one hole
教学相长 teaching others teaches yourself
捷足先登 the early bird catches the worm
斤斤计较 strain at a gnat
尽力而为 do one’s level best
精诚所至 faith will move mountains
静以修身 a light heart lives long
九牛一毛 a drop in the bucket
酒后真言 wine in mirror of the mind
旧情难忘 old love will not be forgotten
局促不安 like a cat on hot bricks
开券有益reading enriches the mind
可歌可泣 set one in a melting mood
空谈无补 talking mends no holes
苦尽甘来 pleasure comes through toil
来龙去脉 cause and effect
来日方长 there will be ample time
烂醉如泥 be as drunk as a lord
老当益壮 there’s many a good tune played on an old fiddle
老马识途 the devil knows many things because he is old
乐极生悲 laugh before breakfast you’ll cry before supper
良药苦口 a good medicine tastes bitter
量力而行 cut the coat according to the cloth
木已成舟 The die is cast
逆水行舟，不进则退 he who does not advance loses ground
