I was received by the Germans in Germany. I want to do as the Romans do. But when Germans come to China, they should follow their customs.

My suggestion is:

1, bathroom requirements: clean and hygienic, dry after taking a shower. So he did it when he was done. Providing bath towels, the German habit is to change them every day. . . Very troublesome

2, the tableware should be clean, and the Germans are cleaner.

Cooking fried steak and potatoes at the end of the first week will make him feel at home. Besides, he should drink cold milk, preferably not instant coffee. Prepare black tea bags. Be sure to ask him if he is a vegetarian! !

4, when eating, say stomach appetite.

Don't disturb him after good night.

6. The time is accurate, even when he gets up, he is usually punctual.

The enthusiasm of China people is OK, and they are generally satisfied.

Happy new year, I hope it helps.
