Thanks for the response, Yingwen. You sound like a professional/expert and very experienced. Are you a director or head of Foreign Language, by any chance?
It has been horrible for me., a nightmare. The FT is from USA, and I am currently living in the USA. That is why I cannot find anyone to at least just notify of the situation. He did sign a specific contract stating he cannot date Chinese students.
Also, in America, teachers do not party with their students and buy drinks and get them drunk. Is there no conflict of interest over there? All I want to know is who to contact or how.
