With the development of science and technology, the application of furniture is more and more extensive. But have you ever thought about what the bookcase will look like in the future?

The bookcase in the future is small in size, easy to shrink and easy to carry. It is divided into three areas: my stack, book market and library. There is also a glass window that can be opened by hand. It is used to deposit money and exchange money. There is a special card in the bookcase, which can be turned on as long as it is inserted into the card reader on one side. Inside is a touch screen. Enter the system and click "Book Market" to enter the book market. In the book fair, a keyboard will pop up, asking you to enter Pinyin, and words that match Pinyin will appear. Click on the desired word and the title of the book will appear. Click on the letters on the keyboard to enter the screen. After entering the title of the book, click "Look Up Books". The system will search for books with the same name. If it is not found, the words "not found" will appear on the screen. If it is found, the price of the book will be displayed on the screen. If you want to buy a book, click "Buy" and put the money in the window, then you can buy a book. The system will accept money, and when it wants to change money, it will say, "Come and get it!" " "If you don't buy it, click' Exit'.

Enter the system and click "Library" to enter the library. The interface of the library is the same as that of the book market. However, after finding the book, you can't sell it, you can only borrow it, and you can only borrow it for two weeks. You can only borrow five books altogether. When the time is up, the record will be cleared automatically.

Enter the system and click "My stacks" to enter my stacks. My bookshelf is full of borrowed books and bought books. There will be two clickable places next to borrowing books: one is "viewing" and the other is "returning books". All the books have "opinions" next to them. After clicking View, the contents of the book will appear on the screen. Click "Return Book" next to the book, and you can return the book.

The bookcases in the future are various, waiting for us to discover and create. Students, let's work together.
