When people type the two characters "apple" in the computer search box, all kinds of information make us dizzy: "Apple Demonstration Park", "Seven Benefits of Eating Apples", "Major Personnel Changes at Apple China", "Apple Bike Shop"... Of all these feedback information, only a small part is what you want. If you are a digital product enthusiast, you may expect to see Apple mobile phones and Apple computers; if you are a fruit wholesaler, you will be interested in the "Apple Demonstration Park"; if you are a lady who wants to beautify yourself, you will look at the "Seven Benefits of Eating Apples".
