What is the purpose of the speaker? To give some advice on how to _______________________a bookstore.

A lot of people want to set up a bookstore. Today, I would like to give some advice on it. First of all，you must choose a good location for your bookstore. Secondly, in your bookstore, customers should have access to the Internet so they can look for the information they want. What’s more, some facilities，which can bring convenience to disabled people, should be equipped；after all，disabled people should have the same opportunities as able-bodied people. Last but not least, it is necessary to hold various activities to attract customers and arouse their interest in reading. I hope my suggestions will meet with your approval.
