    What's the English word for the Chinese food jiaozi? Perhaps you would say "dump ling". But actually, you can just say "jiaozi". It has been officially（正式地）added to the Oxford English Dictionary.

People in English-speaking countries now understand more Chinese words and their spelling in pinyin, according to a recent report by CFLPA（中国外文局）.

The CFLPA studied 50 media platforms（媒体平台）in eight English-speaking countries, including the US, the UK and India. The report listed the top 100 Chinese words that people in these countries use the most.

"Shaolin", a place in China that is famous for kung fu, was at the top of the list. Other popular words include "yin yang", "yuan", "gugong","nihao", "wushu", "qi", "qigong", "renminbi" and "majiang".

Some of the words refer not only to Chinese culture, but also politics, economics（经济）and technology. These words include zhongguomeng（Chinese Dream）, yidaiyilu（the Belt and Road Initiative, 一带一路）and zhifubao（Alipay）.

Why have these words become popular? It may be because of increased interest in learning Chinese. The Confucios Institute（孔子学院）, which offers Chinese lessons, has set up 1,073 classrooms in 140 countries and regions, with 2.1 million students. People's Daily reported.
