If I have to say it myself, I think Houzhen International is still very strong. Judging from their official website alone, the past application records of Houzhen Education are basically universities above TOP30 in the United States. Their background promotion includes scientific research in world famous schools, internships in world famous enterprises, internships in the state government of Hawaii, the Qiu Chengtong Prize for Science, the International Mathematics Competition of the University of Waterloo, summer research projects of the Massachusetts Institute of Technology and so on. In short, they all make corresponding preparations around a core starting point of "sprinting to the top 30 American universities".
