Is it illegal to organize tourism spontaneously?

Who can say that it is illegal to organize, utilize and develop tourism?

However, if we want to develop and utilize it in an operable way, it belongs to the category of administrative management, and we must have corresponding accreditation qualifications and administrative examination and approval procedures before we can develop it in an operable way. Of course, if you organize friends and relatives to visit and play for free, no one can limit you. If you invite me, I will go at my own expense, not to mention breaking the law.
