Is it okay for college students to practice independently and stamp hotel administrators to enjoy it?

You can't. According to the query of China University Student Internship Network, the internship certificate cannot be stamped with the contract seal and financial seal. You can stamp the official seal, department seal or even party Committee seal. Only this contract stamp is not suitable. The contract chapter is mainly used to sign or terminate a labor contract. The financial chapter is mainly a special seal for financial current accounts. So these two don't fit.
