In July 16, 2013 91, Baidu announced a $1 billion 900 million acquisition of a wholly-owned wireless business listed in Hongkong Netdragon, was the largest in the history of the Internet Chinese a merger. In October this year, due to the company's business planning and operation needs, Baidu's related business in Fuzhou R & D center will be moved to Beijing. I understand that Baidu Fuzhou R & D center is currently an innovative incubator sector, which is not directly related to the original 91 wireless. The personnel mobilization and business adjustment are also the adjustment after the end of mobile strategy. But this news, but still triggered the outside of the four years ago on the 91 wireless acquisition of Baidu, and some of the "failure" of the argument. Interestingly, under the interpretation of some "takeover failures", Baidu's stock price has increased greatly. The market value of 115 days has increased by 32 billion 800 million dollars, which is quite impressive.
