German immigration guide, 11 things you shouldn't do
       1.How are you?
       If you really care. The Germans don't like meaningless chitchat, but they are straightforward and honest. Ask the person at the checkout counter or the street vendor who sells you newspapers. Their condition may bring you an angry look. People you know most like to procrastinate in lengthy responses to explain their state of existence. German think you really want to know how you feel when you ask, otherwise you will waste time.
       2.What's your salary?
       Talking about money and a person's salary is taboo. Germans are very private people. When they talk to people they hardly know, they tend to avoid private topics. Of course, friends and family will discuss personal issues, including money, but it's not OK to raise money with people they hardly know.
       3. Call strangers by name
       The conversation between adults who don't know each other starts relatively formal, with people introducing themselves by their surnames and addressing each other by the formal pronoun "Sie" instead of "Du". The official version is always suitable for talking to the elderly or the elderly in a professional environment, but it usually applies to all areas, whether you are speaking to a business partner, colleague, dinner host, bank teller or cashier in a supermarket. When someone "proposes" to use "Du" in the future, both parties will formally agree to use the informal name and name in advance.
       4.I will be late!
       The Germans attach great importance to punctuality. Being late for no obvious reason is considered unacceptable. If you are invited to dinner at 7 p.m., make sure you are on time, not 15 or 30 minutes later – 7 p.m. Don't blame the late arrival of public transport or any other external factors. The Germans want you to arrange more time for you in case you miss the bus or train. However, if you are going to be late, please text or call them immediately and let them know.
       5.May I have some tap water, please?
       Cafes and restaurants usually don't provide free running water, even if you need it. Soda or mineral water is the drink of choice for most Germans, while those who prefer non carbonated water simply order a bottle of distilled water from the menu. German tap water is absolutely safe to drink, but 6.it's hard to drink.
       6.What about the second world war?
       Just don't mention the Second World War. The younger generation is especially tired of facing the history and feeling of darkness, as if they have to explain to others how it happened, why it happened, and how they see it.
       7.Are you an Aryan?
       Most people may realize how objectionable the problem is, though some may use it to infuriate or completely ignorant. Hitler put forward the concept of "Aryan race" to define a "pure" white race superior to others. This question means that you think the German you are talking to is a Nazi.
       8. Do you wear leather pants / dress every day?
       Most Germans may turn a blind eye to this problem. Traditional costumes originated in Austria and southern Bavaria and are mostly worn in folk festivals. In the rest of Germany, no one would think of it unless they were wearing leather breeches or a traditional checkered dress, unless they were on the train to Munich Beer Festival.
       9. Tell Hitler's jokes
       The second world war is still a very sensitive topic. It can be counterproductive to make fun of Hitler in front of people you don't know very well or even in public. Germans, especially the younger generation, sometimes joke, especially about Hitler's way of speaking, and famous German comedians have imitated it in the past, but tourists should not be encouraged to do so. The background and familiarity with the people around are the key.
       10. All beers are the same
       Germany is a beer drinking country. In fact, German breweries produce more than 7000 kinds of beer, from fresh beer to bitter black beer, which is very popular in every region. What German immigrants need to understand is that telling Germans that all beer tastes the same, even among very similar types of beer, can trigger a heated and detailed discussion of nuances.
       11.Happy birthday!
       Before the actual birthday. When it comes to congratulating someone on something before it happens, including their birthday, Germans are superstitious. It is considered unfortunate to do so. It's perfectly acceptable to wish this person a happy birthday in a few weeks. Happy new year to someone, too.
