Born in the countryside of Hebei Province, 49-year-old Zhang Jianna moved to Beijing after finishing high school. She has worked in different jobs, including being a restaurant waitress and working as a salesperson in a shopping center. In 2012, she started working as a city cleaner. However, it was a chance encounter with a foreigner that encouraged her. The foreigner praised the cleanliness of the streets in English, but Zhang could only understand the word " good". This experience developed her interest in learning English. Even though it's hard to find time to study, Zhang used any free time she had to learn new words and practice speaking English. At night, she wrote down everything she learned, filling up many notebooks with what she was learning. She also used English-learning apps on her phone and computer to help her study.
Now knowing about 3, 000 words, Zhang talks confidently with people from other countries, helping them with what they need and showing them around the city streets. Learning English has not just helped her meet people but also made her very happy. "I got more confident from learning, " said Zhang. "I feel joyful every time I help a foreigner. "
Zhang Jianna stands as an inspiring example of lifelong learning and the power of a positive spirit. Her spirit reflects a deep sense of responsibility to present the best face of the capital city to the world. Looking ahead, she hopes to use her English to encourage people to visit her hometown when she stops working and help Hebei Province develop.
