Just like if you want to become a legal citizen of the Chinese nation, you must first have an ID card and a legal account. Without these certification procedures, once discovered, it will not be recognized and will be severely hit!
However, as you said, it is not legal to write the name, function, taboo, etc. on the outside of the package. How to reflect it on the packaging is related to the packaging specifications, not to say how to write it as you want, and the market supervision is getting stricter and stricter. I hope to solve your problem as soon as possible and let the truly effective products help more people.
