在線答疑、課后同類題練習、講義下載、短信提醒You asked me what famous snacks there were in my country. Well, in my country, one of the most famous snacks is tanghulu.
Each different part of China has different tanghulu. It is usually made of haws, which are put together on a stick and covered with ice sugar. But there are more materials for tanghulu today in some places, such as strawberries, grapes, and even little apples.
It is said that tanghulu ever saved the life of an emperor’s wife in the Song Dynasty. It was so delicious and healthy that many Chinese people like eating it. It is now seen as the bright symbols of happiness and reunion.
Are you looking forward to eating it? Come to my country, and I’ll treat you to tanghulu
