As upstairs said, this is a platform built in a mobile communication company to send some information of students during their school days to their parents by SMS. But this belongs to school education and management behavior.

Our public kindergartens here can collect conservation education fees, including management fees, miscellaneous fees, education fees and heating fees during the heating period in winter. Those who provide meals for young children can charge their parents for meals. In addition, public funds are allocated by the finance according to the number of people and used for the daily expenses of kindergartens. Private kindergartens charge a filing system, and the normal expenses of school education management, such as personnel expenses, official expenses, repair expenses, etc. , regarded as the cost of education, is included in the tuition. If there are other charging items, they must be approved by the price department. So to verify whether there are arbitrary charges, you can see if there is this item in the kindergarten's fee permit.

If it is a charge, it must follow the principle of voluntariness, not compulsory and not uniform. I suggest you call "12358" to report the price complaint and consult the local price department.
