他走了茶凉了
[tā zŏu le chá liáng le]
'Ta Zou Le Cha Liang Le', can translate into English as 'he left and the tea became cold'. In a metaphorical sense, this user may want to convey some nostalgia for a departed relationship or person where once there was warmth (like hot tea), but now that someone is gone all is turned cold.
