My friend was held in the second detention center. Is it serious to commit the crime of forced trading?

Whoever forcibly buys or sells goods by violence or threat, or forces others to provide services or force others to accept services, if the circumstances are serious, shall be sentenced to fixed-term imprisonment of not more than three years or criminal detention and shall also or only be fined. In practice, conviction and sentencing depend on attitude, consequences, restitution, surrender, exposure, accusation, meritorious service, principal offender, accessory, minor, recidivist, attempted and many other conditions. The evidence should also be considered. As you said, if conditions permit, you can entrust a lawyer to defend and try to get a lighter sentence.
