Like mother, like daughter. 有其母必有其女。

Like knows like. 惺惺相惜。

Like for like. 一报还一报。

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. 瓮中之鳖。

Life without a friend is death. 没有朋友，虽生犹死。

Life is not all roses. 人生并不是康庄大道。

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

Life is but a span. 人生苦短。
