In Huadu, they had the PGA foundation with the fake ACT after which Beacon College with lies that it was foreign came in. As I have been told, the first program was kicked out for Huanggang could not get the control over the academic evaluation of its students as the company insisted to keep its rights to it, the second program that came with a Hong Kong registered company had Chinese English teachers pre-teaching what foreign teachers then taught there. My bet is that Beacon College (or whatever they call themselves) sold its soul to allow Huanggang improve its high school students' grades. Perhaps, that is how locals say that Huanggang is a famous Chinese school. There is nothing illegal in China till one confronts the local powers, and Huanggang has its school owners in the Huadu Communist Party which is why you are breaking the laws of the nation.
