Is it solved privately or by the local public security bureau after bail pending trial? Or how to solve it? Give high marks

Once the criminal judicial procedure is taken, it is impossible to solve it privately, unless the self-reported case can reach a settlement with the other party on compensation and guarantee, and it will be solved by the public security (public security investigation in the city where the case occurred). Solution: property preservation or personal protection, property moisturizing 1 0,000 yuan or more, deposited in the bank account designated by the executing organ. By the way, I want to find a guarantor, but I can't find one.
