What this case covers

The author is a 45-year-old public sector worker who began making virtual materials on Xiaohongshu in November 2023 and fully invested in K12 Chinese and English courseware in March 2024. The article reviews the workbench process from production and listing to note publishing, as well as paid traffic testing and replication barriers.

Questions it answers

  1. Why does demand for courseware truly exist?
  2. What repetitive actions does the workbench solve?
  3. Does paid traffic affect organic traffic?
  4. Where is the difficulty for ordinary people to replicate?
  5. Is there still opportunity to enter now?

Our observations

  1. Revenue is concentrated in the summer lesson-preparation demand peak, with an obvious time bonus.
  2. Paid traffic is more like expanding total revenue, with limited impact on organic traffic.
  3. Knowing how to use AI is not a barrier; domain judgment is the key.

From the author

Over these two months, I slowly turned a previously very fragmented courseware production process into a relatively complete workflow.
