Is there a universe in the bookstore? Truly a 'Useless Space'

I discovered a very interesting bookstore in the Three Lanes and Seven Alleys of Fuzhou. It covers a large area, and once inside, there's a 'moon' (wall decoration) and 'brain holes' for divergent thinking, and it even hides a winding dry landscape garden... The most interesting part is that the bookstore has a vast collection of books, yet the space looks very open and not cramped at all, with a room like a conference room at the very back. I didn't expect to find such a great place hidden in the Three Lanes and Seven Alleys. The name is 'Useless Space', located in Wenru Alley, close to the location of the Book Fragrance Wenru Hotel.
