Extended information:

QICQ used to imitate ICQ. It is an international chat tool, which means I seek you. OICQ imitates ICQ, which is before ICQ. A letter O was added, which means opening I seek you, which means "open ICQ", but it was accused of infringement, so the boss of Tencent (Ma Huateng) changed the name of OICQ to QQ, which is the current QQ.

Except for the name change, Tencent’s QQ logo has remained unchanged and has always been a little penguin. Because the little penguin in the logo is cute and charming, it has been recognized by girls. In English, it is cute. Because cute and Q are the same pronunciation, QQ is also a good name for the little penguin.
