Extended data:

Qq personalized signature is a function extended from Tencent QQ chat software, which was launched by Tencent in 2005. There is a column of personalized signature in QQ personal file. You can set your own unique personalized signature according to your hobbies and mood.

When friends chat with you, QQ personalized signature is set on the right side of QQ avatar on the chat window.

In every qq account, there are personal data settings, user nicknames (that is, what their names are), and more importantly, personalized signatures. Qq users can write down everything they say and think. Most of their personal signatures are short, but the contents are the essence of classic quotations or emotional portraiture and inspirational phrases.
