Baidu and glutinous rice network are the fastest and most closely combined. After the wholly-owned acquisition in 14, the dense traffic distribution layout began, and a high-level exchange of blood was carried out inside glutinous rice, which completely transformed glutinous rice into a member of Baidu's ecology, and glutinous rice network came back to life. Ali has a delicate competitive relationship with the US Mission because of its "inability to let go" of resources. The US Mission can only rely on its own barbaric growth, and Wang Xing is really capable. Tencent has repeatedly lost in group buying, and finally saw the situation clearly and gave up doing it. It handed over the group buying business to the public comment, and let it develop, which is the most open in BAT. Glutinous rice is the luckiest, and Baidu has the closest combination with it, so that it has not become a nest group and a handle net. The public comment followed, and jumped on the big ship of WeChat in the mobile era. The Meituan is the hardest. Although it has Ali's investment, it does not have the support of Ali's resources, but it is this that brings its luck to grow wildly without scruple.
