Nowadays, people live in apartment which is really close to neighbors in Taipei. But there are seldom interactions between neighbors. And the young generations are smart phone addicts, that they might get lots of information from the internet, but seldom from books.
Place a bookshelf next to the mailboxes of the community. Anyone who wants to share books (or object) can put them in the bookshelf with their name. The bookshelf will be locked after being filled with books and objects, and the conservator will have the key. So if someone fined a book interesting, he or she can send a letter to the owner’s mailbox inform“who and how long they want to borrow what.” After the owners decide to borrow it, they will put the books into borrowers’ mailbox. Therefore people know who is reading their books, might have some conversation in the community.
