Partners in academic circles often share some unpublished achievements. For example, several foreign teachers came to our lab last week, and then when we had a meeting together, the tutor showed them some contents that our group was studying, including some specific data, and then discussed them together. This is a common behavior, communicating with each other. But there is a principle that others show you unpublished things, that is, trust you. You can't use this to do bad things, or even to avoid suspicion, you can't study too similar content, otherwise it will be academic misconduct. PS: When I want to discuss my research with others, I always ask my tutor what I can say first.
The punishment for academic misconduct in China is too low, and teachers are found to have serious behaviors such as plagiarism. There is no room for improvement in the next few years at most, and there are almost no negative problems. For example, a professor in our college was sued for copying other people's books and lost the case. Nothing happened. Hehe, it is estimated that this matter will be dealt with in the end.
