【題目】 Li Yanhai,13, Liaoning

I taught my mother the catchword ( 流 行 語 ) “Zhaxinle, Laotie ”. “Zhaxinle”means “You’ve broken my heart.” and “Laotie” means “homie”, which refers to a very close friend of yours. It’s a popular sentence from the northeast of China and now widely used by people around the country.

Zhong Yunfei, 13, Beijing

It’s not easy to teach parents catchwords. Last month, I tried to teach them, “The baby suffers (忍受) inside, but he doesn’t say a word about it”.

I told them that “baobao” could refer to the speaker himself or herself. They said it was cute.
