As for the requirements of these positions, first of all, you should have a tour guide certificate, and second, you should look at your personal working ability, such as taking a tour group and explaining scenic spots and tourist areas.
It's hard to say whether being a tour guide is good or not. It depends on personal understanding. There is no difference between good and bad work, and what suits you is good. To be a tour guide, you must be cheerful, talk, laugh, be in charge of the overall situation and coordinate the whole team. In addition, we must be careful, because there are many trivial and complicated things to take with us. Emotional intelligence should be high, know how to get along with people, resolve contradictions and coordinate the atmosphere.
To emphasize one point, it is actually very hard for girls to be tour guides. No matter whether it is cold or hot, they have to run around outside and get up early when they meet a group. That's about it. You can ask me more questions.
