With the development of intelligent mobile terminals and the popularity of social communication networks, the social communication scope of an intelligent mobile terminal user is greatly expanded. Therefore, the mobile terminal user has lots of contact information to manage. The current contact management manner has some obvious disadvantages in managing large amounts of contact information. For example, a contact is difficult to search for or find because the contact is generally searched for by using the first letter of an alphabetic identifier of the contact, that is, inputting the first letter of the contact in a contact search box. Because the contact information is huge, a large number of contacts having the same first letter may be searched out or found by using the first letter. These contacts having the same first letter are all displayed. In this case, the user is only capable of finding needed contact information by browsing or scrolling pages. This process is time-consuming, and does not satisfy a user's expectation for quickly searching for and locating a contact. In addition, user experience on the intelligent mobile terminal is reduced.
