OK, I will give a little introduce to you foreign guys:
Taobao is a B2C/C2C E-commerce site.
11/11 is called Single's Day(all number is '1', you see?), as some song sings, "single boy single boy.single all the way!".
Taobao is one of the three biggest IT company in China. It is composed of taobao(C2C), tianmao(B2C), alibaba(B2B), yahoo China and etao(shopping search).
Moreover, you must know that on October 30, 2012, China's largest online book retailer, oldest B2C electronic business, the first landing Nasdaq China's e-commerce company, Dangdang, declared to join Tianmao.
Finally, I should say as Ma-yun said : I am very cruel, more brutal tomorrow, the day after tomorrow is very beautiful, but most of the dead tomorrow night, only those who are the real heroes to see the sun on the day after tomorrow.
single boy, single boy, single all the way!
single man, single man, single all the way!
