Dear Sarah,
Thank you for your letter asking about the rebuilt Oianmen Street. Here is something about it.
Qianmen Street is a famous street of over 600 years old. Along this 800-meter street, there are more than 300 shops. As the street is in the center of Beijing, just to the south of Tian’anmen Square, it’s very convenient to get there by bus. You may take Buses No. 17, 69 or 59. Subway Line 2 has a stop there too. Qianmen Street is a pedestrian street, but there are trolley cars to take you not only to the shops, but also to theatres and teahouses where you can experience a truly Chinese way of life. I’m sure you’ll like it.
Yours,
Li Hua
