What etiquette and etiquette issues should you pay attention to when traveling to the UK?

British etiquette is rich and colorful. When people first meet each other, they usually shake hands as a courtesy, unlike Eastern Europeans who often hug. It is considered indecent to slap a guest casually, even after official business is over. There are some taboos that the British need to pay attention to, such as they never walk under ladders, do not hold umbrellas in the house, never put shoes on the table, and decorate with portraits, etc. The British pay attention to clothing and dress differently depending on the time. They tend to judge people by their appearance, so pay special attention to appearance and attitude. The British are very particular about how they dress. As soon as they leave home, they must be well-dressed. Although the British no longer have the glory of the past, they are extremely conceited. Because people in the middle and upper classes live a comfortable life, they have developed a traditional "gentleman" and "lady" demeanor. But they are conservative and generally keen on sticking to the rules and being reserved and dignified. Most families like to show off old furniture, old furnishings, and old clocks passed down from previous generations. There are many "century-old stores" in London, the capital, and the more famous the store, the more complete it maintains its original style or layout. Although the car engine has been replaced with a new model, the car model should try to remain the same as in the past. There are two post offices in London, which are open day and night 365 days a year and never rest. It is said that this is preserved in accordance with the ancient British tradition. British people are withdrawn, rigid in life, serious in doing things, not interested in external affairs, often taciturn, cautious about new things, and have a unique calm humor. They are conservative, indifferent, and don't reveal their emotions. Even if they have very sad things, they often don't show it. They rarely lose their temper, are patient, and are unwilling to have meaningless arguments with others. The British are very patient and never show any signs of anxiety under any circumstances. British people are polite to others and speak very politely. They always say "thank you" and "please". You must also be polite when speaking to British people. No matter they are waiters or drivers, you must treat them politely. When you ask them to do things, you must speak tactfully and don't sound commanding. Otherwise, you may be treated coldly. The British respect women more. In the UK, the social atmosphere of "ladies first" is very strong. For example, when walking, let women go first. Let women go first in the elevator. When taking a bus or tram, let women get on first. When pouring wine, the female guest or hostess should pour it first. When walking on the street, men should walk on the outside to avoid danger and to protect women from harm. Husbands usually participate in various social activities with their wives, and they always introduce their wives to VIPs first. According to British business etiquette, it is appropriate to wear a three-piece suit and a traditional conservative tie at all times, but do not wear a striped tie, because the British will associate it with the old "legionary" or old school uniform tie. British people have a strong sense of time. When visiting or discussing business, you must make an appointment in advance. Punctuality is very important. It is best to arrive a few minutes in advance. The way they get along is to strictly keep time and keep their promises.
