So after some investigations, I found out at least qirou yang, lifan Zhou and Sophia oppel paid wang zi who was also herself a scammer to fake graduate schools, degrees, exhibitions, festivals and jobs in order to illegally immigrate. They have neither jobs, experiences and schools or anything like it. It probably cost 6000 to 10000 dollars. Recently I found out they are probably back in Canada from China while having no jobs or anything prospects. All they do all day is to harass people, stalking them. It’s unbelievable. They turned their social media to private settings or just faking stuff on there.
