When a British tourist in a tour group visited Nanjing Purple Mountain Observatory, his words were quite arrogant. He thinks only British astronomy and English.

If you are a tour guide, there is no need or direct conflict with him.

First of all, you must confirm his statement that Greenwich Observatory is indeed one of the first-class observatories in the world, which is why I think Nanjing Purple Mountain Observatory is equally important. Astronomy is the cause of all mankind, and the people of China are willing to work together with the friendly British people for a better tomorrow for all mankind. Moreover, Nanjing Purple Mountain Observatory is the base point for measuring the western Pacific horizon. "

Agreeing with others' ideas can soften others, but it doesn't mean you have to give up your position. While affirming him, make yourself more tolerant and the other person will be guided by you.
