猫九凉七
[māo jiŭ liáng qī]
'Mao Jiu Liang Qi', this Chinese online name combines the elements that do not seem directly connected to foreigners. '猫(Mao)' is 'cat'. And '九(Jiu)' plus '七(Qi)', two numbers without specific meaning as they are. Possibly for Chinese netizens with pet cats, it could be used casually and have a unique significance for its owner.
