Hehe, I suggest you take an English tour guide qualification exam and study Tourism English systematically while reviewing. If you pass the exam and get the certificate, you can kill two birds with one stone.

Teaching material recommendation

I recommend several textbooks: English for Tour Guides, English for Foreign Tour Guides and Longman Tourism English (elementary, intermediate and advanced). The first two books are domestic, and the first one can be used as a training material for tour guide qualification certificate; Third, foreign original textbooks are interspersed, complement each other and grasp the key points.

Tourism project recommendation

Watch some English travel programs, whether it's Travel, which is produced by CCTV to introduce the scenery of China to foreigners, or Lonely Planet, which is known as the "yellow bible" for travelers, which is an excellent audio-visual teaching material.

Travel more.

Of course, it's better to take Wan Li Road and study in thousands of books. If you have the conditions to travel more, you will have a more intuitive feeling and help to better understand the tourism industry.
