Do bounty hunters really exist?

Bounty hunters do exist. There are bounty hunters in reality, but China doesn't. There are bounty hunters in America. In the United States, due to legal and cultural reasons, bounty hunters are still active all over the country, but now there is a more civilized title "bail guarantor". If a released criminal employed by a bail institution fails to appear in court as scheduled, he will be responsible for bringing him back and collecting 10% bail as a reward. The laws of every state in the United States are different, but now bounty hunters basically need to be certified, and they must continue to participate in the education and training organized by the bail association and pass a complete background check.
