1. Shift of focus: In the video released in February, 202 1, 65438, I told Mr. Bo that I needed to concentrate on teaching and had no extra energy to make a video, so I decided to stop updating. It may also be that he decided to focus on teaching and scientific research instead of continuing to update the vibrato video.
2. Platform selection: Mr. Xiang Bo may decide to publish content on other platforms. After Tik Tok platform stops updating, he can continue to share his teaching contents and knowledge on other platforms.
3. Creative bottleneck: In the long-term creative process, there may be a lack of inspiration or some difficult creative problems, which may also lead him to temporarily stop creating videos.
In short, Mr. Xiang Bo didn't update the video because he wanted to concentrate on teaching and research, or he wanted to continue to create on other platforms.
