Can bodyguards testify in court?

To testify in court, bodyguards can appear in court. According to relevant data, on September 10, 2022, a district court in Changsha tried a very special case, and needed the help of witnesses to testify in court, but the witnesses were afraid to appear in court for fear of retaliation by the defendant's family. Finally, the plaintiff hired a bodyguard from Changsha Xiyudun Bodyguard Company to testify in court, and was willing to pay the bodyguard to protect the female witness for a period of time, and the female witness was also willing to testify in court. At the first trial, the criminal was sentenced to death and will be executed at the end of the year.
