As a rule, the terms 'education center' as part of a Chinese school's name should be enough to start alarm bells ringing loudly in your mind. Of course, it is just a fancy expression for a TC (or training center). Most of them are run by unscrupulous Chinese who are not averse to abusing any foreigners who come into contact with them. That 'school' is an absolute disgrace regarding the shabby and deceitful way it treats its foreign teachers! Yuming Education Center of Tianjin is certainly minging as an employer, and should be put out of business sooner rather than later by the relevant government authorities of the city.
