My friend built a kindergarten in Luoyang, a third-tier city, and the business is ok. A few years ago, I joined Hong Ying, and a complete enrollment, operation and training system improved the teaching quality and the number of students in my kindergarten.
How much you invest in kindergarten depends on your own positioning. Generally speaking, if you don't do preschool education, you can hire professional principals and teachers.
In a metropolis like franchise chain, it is certain that some people do well and some people do badly, which is related to the quality of directors and supervisors. Most of them are good. As long as you follow the requirements step by step, you can get a lot of improvement and development.
