Alibaba Video and Douyin are two different applications with different content, users and functions. Therefore, Alibaba Video cannot directly upload Douyin videos. If you want to share your video content on Alibaba Video, you need to download your video from Douyin to your device and then upload it to Alibaba Video. However, it should be noted that you need to make sure that you own the copyright of the video or have obtained relevant authorization to avoid infringing on the copyright and intellectual property rights of others.
