I want to rent a CD and a bookstore.

Don't rent CDs. The timeliness of CD is very high. Too many people rent a TV or movie when it is broadcast. After a while, few people cared. The update rate of the CD is too high. As soon as there is a new movie, it is necessary to purchase a new TV series, otherwise it will be difficult to retain tenants. This was a few years ago. Now people watch it online. It's convenient if they want to see it. You don't have to wait in line like renting a disc.

I suggest you rent some books. Although many books can also be read online, people who love reading know that reading: the feeling of holding a book in your hand is completely different from staring at the screen. The update rate of books is much lower than that of renting CDs. Of course, the magazine is updated every month.
