The wise man knows he knows nothing, the fool thinks he knows all. 清者自清，濁者自濁。

The water that bears the boat is the same that swallows it up. 水能載舟，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. 書山有路勤為徑，學海無涯苦作舟。

There is no place like home. 金窩銀窩不如咱的狗窩。

There is no medicine against death. 沒有長生不老藥。

There is no general rule without some exception. 任何法規均有例外。

There is kindness to be found everywhere. 人間處處有溫情。

There is a skeleton in the cupboard. 家家有本難念的經。
