Like knows like. 惺惺相惜。

Like for like. 一報還一報。

Like father, like son. 有其父必有其子。

Like author, like book. 文如其人。

Like a rat in a hole. 甕中之鱉。

Life without a friend is death. 沒有朋友，雖生猶死。

Life is not all roses. 人生並不是康莊大道。

Life is half spent before we know what it is. 人過半生，方知天命。

Life is but a span. 人生苦短。

Lies have short legs. 謊言站不長。
