Since last week, the slogan of "boycotting Carrefour" has been spread through online forums, chat tools and mobile phone text messages. Netizens called on web users in all places to refuse to go shopping in Carrefour on May 1st in the form of "mobilization order", "to boycott together with their relatives and friends." Some network rumors said that Carrefour prepared to cut down prices to promote sales during the May Day to respond to netizens' opposition.
