Questions about the Cixi "grope gate" incident?

Question one: In the Cixi "Molestation Gate" incident, those students were reported to have collectively molested women in the classroom. Where was the teacher who was supposed to be giving the lesson? Could it be that the leaked 3gp video was filmed by him?

Question two: In the "Molestation Gate" video, we noticed that the female victim showed absolutely no signs of resistance, and even when someone licked her, she did not resist. Was she too afraid to resist or did she do so willingly?

Question three: My friends at the vocational high school all say they don't know this girl and have never seen her before. Could it be that this "Molestation Gate" video is fake and the people involved aren't actually students from Cixi Vocational High School, but instead actors or AV performers?

Question four: Who filmed this video and who uploaded it? From the video format being 3gp, we can tell that it was definitely filmed with a mobile phone.

Question five: The filming of the "Molestation Gate" video should have taken place in April because the weather in Cixi was already very hot, yet the woman in the video was wearing a jacket, so it certainly wasn't filmed recently. If it had already been filmed in April, then why was it only released in July?
