Some training schools are very strict with their members. I know this better. I hope it will be helpful to you! For example, the ace shield bodyguard company in Beijing has extremely strict requirements on the source quality of its members. It only includes recent special forces veterans who meet 27 international standards and are re trained and assessed. They all have profound practical fighting skills, rich experience in handling social affairs, excellent psychological quality, strong loyalty and strong sense of responsibility. You can contact their staff and ask you to fill out a form. In addition, private bodyguards are a sacred profession. Not everyone can be competent. You should be responsible not only for yourself, but also for your employer. Please consider it carefully!
