Threatening each other and causing crime? (Beating him or something) Is there a charge for just saying that?

What constitutes the crime of intimidation depends on the content and purpose of intimidation. If it is to obtain illegal benefits, it may be suspected of extortion. If it is to obtain money, threatening violence and obtaining property on the spot may constitute robbery. If there is no special purpose, it may be suspected of causing trouble. If it does not constitute a crime, it may be punished in accordance with the regulations on administrative penalties for public security. Therefore, it is best not to do such a thing. Judging from what you said, it should not have reached the seriousness of the crime. However, tort compensation requires actual losses, which seems to be non-existent. Therefore, at most, they will be punished by public security, educated, warned and fined. From what you said, there should be no administrative detention.
