The Beijing Book Building is the largest and most complete shop in Beijing. The subway entrance is not far away. There are always many people who buy books, and many people who sit on the ground reading books, besides books, there are other commodities to sell. Sometimes there are activities and there are many discounts. I like to visit the original books on the ground floor. Although they are very expensive, they have a wide range of books and can always buy the new ones I like.
