There is news that 12 Chinese cities are bidding for 2036 Olympics after Brisbane was announced to be the host city of 2032 Olympics. These cities include Nanjing, Shanghai, Guangzhou, Shenzhen, Dalian, Xi'an, Chengdu, Jinan, Xiamen, Zhengzhou, Wuhan and Suzhou. But I think it's a rumor.
We Chinese people do want to host an Olympic games again, because Beijing 2008 left us with wonderful memories. But when and where to host this game is something to consider carefully.
One of the reasons why I don't think these 12 cities won't bid for 2036 is the authenticity of this news. None of the cities have come up with official bid plans. None of them have even told the media or written in the government working report that they were willing to bid. On Chinese official media like Xinhua Agency, People's Daily, CCTV, there is no report on the bid plans.
I first saw the news of 12 cities' bid on my QQ zone (a platform to show yourself, just like twitter or Facebook). It was screenshots of some webpage of non official Internet media, which didn't indicate who the author of the news is. The source of the news is unknown.
So I guess that the news was released by some "Yingxiaohao", a kind of accounts that often post some eye-catching, grandstanding, and sometimes forged articles or videos to gain attention. Many Chinese Internet users can't distinguish true from false, making these rumors easier to spread.
