It allows users to view their friends' basic information, categorize their posts, and keep track of recent chats. Users can also receive various types of messages including system messages, friends' messages, and recommended sales messages.

3. Contact List: This module is designed to help users manage their contacts effectively. It provides features such as adding recommended friends, automatically setting friends if both parties' phone numbers are in the contact list, and setting a blacklist.
