From your description, you should prefer the second one, right? I used to train children, and I also inspected the related online learning system during the epidemic. The reason why I choose to open my own shop is because the threshold is relatively low, and I can directly use the existing technology of the system to realize my own functional requirements. In addition, the operation will not be strongly interfered by the platform, and it is more convenient to call the WeChat system to pull new activities.
Simple books are relatively cheap. I chose the simplified book after consideration, and I still use it now. It feels quite convenient. Made a small profit during the epidemic. I'll see if there is room for renewal later.
