On August 4, QQ Whirlwind, which has operated for nine years, released a "QQ Whirlwind Offline Announcement" on its official website, which mentioned that "due to the adjustment in business development, 'QQ Whirlwind' will stop operating on September 6, 2017." The classic download tool of the first generation has been retired after nine years of operation, but this is not Tencent's first product to give up recently. In March this year, Tencent's short video sharing community Microvision announced that it would shut down the service on April 10, and suggested that users log on to the official website of Microvision and enter their personal pages to download and save videos. In July, another Tencent product, Youren, also announced that it would stop operating. Tencent said, "Due to the business adjustment, Friend. com will stop its service and operation on August 6, 2017. It is recommended to download and backup your photos
