Qq personalized signature is a function extended from Tencent QQ chat software and was launched by Tencent in 2005. There is a personalized signature column in your QQ profile. You can set your own unique personalized signature according to your hobbies and mood. When a friend chats with you, the QQ personalized signature is set to the right of the QQ avatar on the chat window. In every QQ account, there are personal information settings, user nicknames (that is, what their names are), and more importantly, personalized signatures. Qq users can write everything they say and think. Most of their personal signatures are short, but the contents are the essence of classic quotations, emotional portrayals, and inspirational phrases.
