I live in Germany. Germans generally love cleanliness, and my home is always spotless, including the bathroom. Many families have dogs, and dogs have a high status in the family. As for whether to take a bath with cold water, what you are interested in must vary from person to person. Just like before I went abroad for the first time, someone told me that if you don't know football, you won't have the same language as the Germans, but when you go abroad, it's not the case at all. Many people are not interested in football. One thing to note is that Germans eat separately, that is, a big pot or a plate of things is put on their own plates with public tableware, instead of us in China reaching for chopsticks and spoons. Moreover, Germans eat quietly, while China eats loudly, which is also widely criticized in Europe. However, I think eating loudly in China is a symbol of good luck. Do we have to move closer to Europe? There is nothing else to pay attention to. It would be nice to show them the following hospitality in China, wouldn't it?
