Two mobile phones and one tablet computer are playing live pictures of different platforms and anchors on the screen. The anchorman introduced various commodities either enthusiastically or confidently. Dai Ying (a pseudonym), a resident of Haidian District, Beijing, sat in front of three sets of equipment and carefully recorded the commodities and prices to be purchased on the notebook. With the sound of "three, two, one, link up" on the screen, Dai Ying quickly picked up her mobile phone or tablet computer for a quick operation. Then, her frown slowly spread, revealing a satisfied expression, as if she had won a battle in just a few seconds. Dai Ying has been fighting on the "three fronts" for nearly two weeks. At the end of October this year, the "Double 11" activities of major e-commerce platforms began one after another, and the live broadcast room became the main battlefield. "I feel that the price of the live broadcast room is much lower than the usual price, especially for several major anchors. There are a lot of people in the live broadcast room. If I don't stick to my guns, I may be robbed." Dai Ying said that she had bought more than 20 items during the "Double 11" period, from the advance deposit to the first wave of final payment, all of which were placed in the live broadcast room. Like Dai Ying, there are not a few consumers who mainly rely on the live broadcast room to purchase goods during the "Double 11" period. The main reason why they chose the live broadcast room was that they believed that the live broadcast room would be much cheaper than usual because of its great discount. Many consumers also said that there are often welfare activities such as "red envelope rain" and "top 1000 people order and give gifts" in the live broadcast room, which makes people have a strong desire to participate. However, is the live delivery during the "Double 11" really cost-effective? Is there any basis for "the lowest price of the whole network", "the price breaking live broadcast" and "the price falling below the floor" that the anchors constantly emphasize? The "former ×× Is the promise of "purchase with good gifts" credible? With these questions in mind, the reporter of the Rule of Law Daily carried out an investigation on the live delivery of goods on various e-commerce platforms during the "Double 11" period. During the promotion, the hot issues related to the live broadcast were followed by "Beauty, the annual" Double 11 "is coming again" "Treasures, I have asked you for the lowest price of this product ever. Remember to buy it" "Only our fans in the live broadcast room have this benefit. You should hurry up to buy it"... The "Double 11" promotion activities are going on in full swing on all major e-commerce platforms, and the atmosphere of goods in the live broadcast room is hot. From the head anchors with tens of millions of fans to many new small anchors, as well as many stars and online celebrities, they have successively joined the trend of e-commerce live broadcast, and frequently appeared on the screen to bring goods during the "Double 11". Tmall's "Double 11" data shows that in the first hour of sales on October 31, Taobao's live broadcast increased by 600% year on year, and the waist anchor's trading volume increased by 250% year on year.
