Math blunder

Police officials in Nanjing city of Jiangsu province post a weibo to question Alibaba's statistics on Nov 11, 2013.

E-commerce provider Alibaba might have made a math mistake while celebrating Monday's Singles Day shopping spree.

The company said it sold 2 million pairs of underwear in one hour, which would make about a 3,000-km link. A Sina Weibo post subsequently said that means a single pair of underwear was 1.5 meters long, and that cannot be right. The post written in a humorous tone was forwarded 75,416 times.
