There is training. When you sign up, the travel agency tells you when to train, and you have to pay.

You can buy books and read them yourself, but the training will focus on the key points and it is still necessary.

The above is to answer your question, but personally, it seems that you are not a regular employee of the travel agency and are not qualified to sign up at all, so you don't know the above situation. If you want to take a tour guide card, you must first become a full-time employee of a travel agency.
