Working on trending topics on Weibo can be beneficial because it allows creators to reach more people, increase views and engagement when used wisely. When you create on a viral or trending topic, Weibo's algorithm will reach your post to more people, giving you the opportunity to gain brand new followers. If a trend is related to your niche, creating content on it can also benefit you. But if you chase every trend, your audience will get confused and your account will lose its identity. Therefore, it is better to stay in your niche and join only those trends that match your content. This way, you will also get reach and your brand value will not be damaged.
