November, 11 in China is the "Day of Chinese Bachelors", as well as a day of grandiose sales. The Internet retailer Alibaba arranged its first sale in 2009, which was attended by only 27 sellers, according to the company's records. In recent years this tradition was taken up by Chinese shopping centres and online retailers. In 2016 Alibaba earned its record $17.8 billion during one day of sales.
A bachelor's day is a holiday for people who are not burdened with family life. This day Chinese people actively participate in online shopping. So November, 11 has become a kind of day of Internet shopping.
