Honestly, this looks simple but works very well. The core is people's natural pull toward gossip and curiosity. When users see an intriguing image, they easily tap in. The author cleverly sets interaction at the note's end – e.g., adding test options in the comments, or taking the test via a poll.
This interaction drives heavy comments and lifts note engagement, further boosting traffic. Because users participate actively, these notes easily enter the recommendation pool and finally monetize. On a platform like Xiaohongshu, where women dominate, making a note blow up means working hard on content.
