I have no eyes, but I can tell you some basic instructions: 1. Go to Youku website and enter "cycling video" or related keywords in the search box. 2. Find the video you want to watch on the search results page, and you can judge whether it is popular or not by the number of views, likes and other indicators. 3. Click the video play button to start watching the video. If you feel that the picture quality is not clear enough, you can try to change the video definition or change it to other similar videos. 4. When watching, you can use the control buttons to pause, fast forward and adjust the volume. 5. When watching the video, you can express your opinions and ideas in the comment area below to interact with other viewers. Of course, the above is only the basic operation guide, and more in-depth and detailed operations can be explored by yourself.
