Hello, In answer to your question "you ask which cambridge school is this?" If it is Chinese owned it has nothing at all to do with Cambridge. It is just a deception at getting credibility by using the noun name "Cambridge"
If it is a partner school with Cambridge university, they would be required to state this in all advertising.
If it is a Franchise school of a LTD UK education company using the name Cambridge, that is ok so long as the school keeps to the conditions by which it is allowed to be a franchise school.
It is wise to ask them to idenitify their relationship with Cambridge before working for them.
