2. If you don't mention too much reputation compensation in this kind of case, the facts of the case are clear, the evidence is convenient and the lawyer's fee will not be too high. It is estimated that it is only three to five thousand, and the fees charged by each law firm are different. I suggest you consult a law firm more.
3. You should prepare the identity certificate of the other party (defendant) and concrete evidence of reputation damage, such as various written, electronic (video, computer) and witnesses. The more detailed the preparation, the better. The lawyer will guide you.
I don't quite understand what the so-called case reservation means. All cases that enter the lawsuit will not be judged unless they are withdrawn.
I hope the above points are useful to you.
