It's 2022 now. Xu Xiuzhen is 77 years old. Recently, videos of her talking with foreigners become popular on the Internet. In these videos, she speaks different languages with them.

Xu has been working as a tour guide and vendor in Yangshuo, a county in southern China’s Guangxi Zhuang autonomous region since 1998, when the area became famous with foreigners and organized tours. Xu dropped out of junior school in the third grade. To make a living, she began to learn different languages in order to encourage more foreigners to buy things. Over the past twenty years, Xu has taught herself 11 foreign languages, including English, Spanish, Japanese and Korean. It makes her popular, and her excellent language skills have also made it easier for her to communicate with foreign tourists.

Xu said she would convert(转换) words in any language into Chinese characters according to their pronunciation and then memorize them. Repeating the words in her head before going to bed and right away after waking up has made her talk with foreigners well.

Xu has also become one of the busiest tour guides in Yangshuo. Her reputation(名声) draws a large crowd of tourists every day, especially foreign visitors, who come to meet the special guide out of admiration. 

“More and more foreign tourists are coming to Yangshuo, and I hope they will feel at home here with my help,” she said.
