Take early education as an example, brands generally train themselves, and the training certificates issued are only valid within the brand. Of course, some factions, such as Montessori, have a particularly wide range of training certificates, which can be recognized in many places.
In other words, you are a baby nurse, you can do early education, and you can also do any work related to baby-rearing.
But you don't have to be a nanny to do early education.
As for the treatment:
Being a nanny depends on your level first. The higher the level, the higher the starting point of treatment, but the specific salary depends on your specific job. If you work as a full-time nanny in a rich family, your salary is also a big white-collar worker.
If you are a teacher, the salary of foreign brands will be higher and that of local brands will be relatively lower.
