The tall building that I like is a central library of my city. More than 40 floors I might say. 2 years ago it was being built, now it has been a part of our city life. The landmark of my city. Include the study area, most of the floors are filled with free Wifi, and certainly the coffee area and media rooms in general. I can say that it is used for the public, to improve our study habit I guess. It looks exactly like an old book if you watch it from outside world. I have been there many times, during last summer vacation, I have been there more than 10 times, just for my study you know. Besides, it is open to the public 24 hours each day. This is the point. I love it. Especially after a hard day of work and study, I could find such a proper place to rest my mind and read some periodicals or magazines. Quite comfortable environment. Only problem that I have to think about its the reservation. Because most of the time, the seat is usually occupied, I have to deal with this problem, you know. So, this is the tall building that I like to visit in my city. That is it.
