Being on sea, sail; being on land, settle.
随遇而安。

Be slow to promise and quick to perform.
不輕諾，諾必果。

Better an empty purse than an empty head.
甯可錢袋癟，不要腦袋空。

Better an open enemy than a false friend.
明槍易躲，暗箭難防。

Better good neighbours near than relations far away.
遠親不如近鄰。

Between the cup and the lip a morsel may slip.
功虧一篑。

Between two stools one falls to the ground.
腳踏兩頭要落空。

Beware beginnings.
慎始為上。

Big mouthfuls ofter choke.
貪多嚼不爛。

Birds of a feather flock together.
物以類聚，人以群分。

Bite off more than one can chew.
貪多咽不下。

Bite the hand that feeds one.
恩将仇報。

Bitter pills may have wholesome effects.
良藥苦口利于病。

Blind men can judge no colours.
不宜問道於盲。

Blood is thicker than water.
血濃于水。

Bread is the staff of life.
民以食為天。

Bring up a raven and he'll pick out your eyes.
養虎贻患。

Burn not your house to rid it of the mouse.
投鼠忌器。

Burnt child dreads the fire.
一朝被蛇咬，十年怕井繩。

By doing we learn.
經一事，長一智。

By falling we learn to go safely.
吃一塹，長一智。

By other's faults, wise men correct their own.
他山之石，可以攻玉。
