Would you like to know me?
Hello! My name is Annie. I’m from Nantong, China, which is a small city near Shanghai. And my hometown is famous for its seafood. My mum and dad live in the same city. And I have a little sister. She is fourteen years younger than me. I live together with my husband and son together.
I graduated from (a) nursing school many years ago and worked as a nurse in the biggest hospital in our town. At the age of twenty-eight, I became the youngest head nurse in our hospital. After about thirteen-years of work, I got a teaching license of teaching through self-study, and began to teach general technology in a high school.
I’m crazy about learning English. So in my spare time, I study New Concept English I, II, III, and other studying materials. Sometimes I hang out with my friends. And I like jogging and yoga. I think I do benefit a lot from regular exercise.
In the future, other than doing my work well, I will continue to study English and try to polish (up) my English level, and I hope I will be able to communicate with foreigners fluently.
Thank you!
