Often seen in online chats and online novels, this combination of letters looks like the emoji of two weeping eyes and a wide open mouth, and therefore is used to mean “very sad.” People often type it at the end of a sentence.
Gāokǎo zhōngyú jiéshù le，nǐ kěyǐ hǎohǎo fàngsōng yīxià le。
Gaokao (the national college entrance exams) is finally over. You can give yourself a break now.
Wǒ gǎnjué shùxué shìjuàn tài nán le，kǎo de bù hǎo，QAQ。
I feel the math exam was very challenging and I didn’t do well. (Weepy face)
Kǎo wán le jiù búyào zài xiǎng le，yīchǎng kǎoshì bìng bù juédìng nǐ de wèilái，yǐhòu de lù hái cháng。
Don’t think about it now that it’s over. The exam doesn’t decide your future once and for all as you have a long way to go.
