The water that bears the boat is the same that swallows it up. 水能载舟，亦能覆舟。

The tongue is not steel, yet it cuts. 人言可畏。

The style is the man. 字如其人。

There is no royal road to learning. 书山有路勤为径，学海无涯苦作舟。

There is no place like home. 金窝银窝不如咱的狗窝。

There is no medicine against death. 没有长生不老药。

There is no general rule without some exception. 任何法规均有例外。

There is kindness to be found everywhere. 人间处处有温情。

There is a skeleton in the cupboard. 家家有本难念的经。
