How does the Weibo algorithm decide which posts to promote?

I've been trying to understand how the Weibo algorithm works. What factors seem to influence whether a post gets promoted to a wider audience? Does it prioritize early engagement, trending hashtags, posting time, follower activity, or overall content quality? I'd be interested to hear your experiences and any insights you've gained from using the platform.

weibo tends to focus on hi vis keywords .

From my observation it appears like engagement and consistency are the most important qualities to possess while utilizing this platform.
