QQ is an Internet-based instant messenger (TM or Tencent QQ for short) independently developed by Tencent/KLOC-0 in February, 1999. Its reasonable design, good application, powerful functions and stable and efficient system operation have won the recognition of users. QQ used to imitate ICQ, which is an international chat tool. It means I'm looking for you OICQ imitates ICQ. It added an o in front of ICQ, which means "open me to find you", but it was accused of infringement, so Tencent's boss (Ma) changed the name of OICQ to QQ, which is the QQ we use now.

Except the name has changed, the logo of Tencent QQ has not changed, and it has always been a little penguin. Because the little penguin in logo is cute and charming and highly recognized by girls, it is cute in English. Because cuteness is homophonic with Q, it is also a good name given to the little penguin by QQ.

QQ for Linux is an instant messaging software based on Linux platform released by Tencent on July 3rd, 2008. Mainly used to clean up third-party QQ on Linux platform. However, QQ for Linux has ceased to be used, and official WebQQ is provided across platforms, with few updates, and its function has lagged behind other desktop clients. Ubuntu Chinese has launched users to complain to Tencent customer service, but it has no real effect. Tencent has also been blocking related third-party QQ software, and it is extremely difficult for Linux users to use QQ.
