As far as the current situation is concerned, the tour guide card is definitely not worth it, because the use is basically zero and the time cost is high. If you really have more time and want to read more books to enrich yourself, then it is no problem to take the exam. If you want to visit scenic spots for free, most scenic spots will not be free just because you have a tour guide card. Basically, only group tours will be free. And you have to pay a fee to the affiliated travel agency or the local tourism management agency every year.
Considering the end of the epidemic in the future, in fact, many people have the same idea. After the epidemic, everyone will take revenge tourism, which is a good opportunity for tourism development. However, when will that day come, because the economic impact of the epidemic will not make everyone have the financial resources to play around. Even if the first two questions have no influence, having a tour guide card may not necessarily make money, because taking a tour is not an easy task and requires a lot of practical operation and various abilities. When there is no epidemic, not all tour guides can make money, and many people change careers every year.
