1. What is How do you do?
Typically, English learners often confuse How do you do as an inquiry about health, similar to How are you, but in fact, this phrase is not used for that purpose.
According to the Cambridge Dictionary, How do you do means How have you been lately? A formal greeting for someone you haven't met before (translation: a formal greeting for someone you haven't met before)

Therefore, How do you do is used as a greeting for someone you meet for the first time, in a very polite and formal context. This is not a question about someone's health, even misunderstood by many people
E.g.:
- Greetings, my name is Edward Black. (Xin chào, tên tôi là Edward Black.)
- How do you do? I’m Jacqueline Smith. (Xin chào. Tôi là Jacqueline Smith.)
2. How to use the structure of How do you do in English
The structure of How do you do is often used in situations of first meetings or in formal and solemn contexts (meeting business partners, meeting people of high status,…).

2.1. Situations where the structure How do you do can be used
Gặp gỡ lần đầu
- A: How do you do?
- B: How do you do?
Trả lời câu How do you do? từ đối phương
- A: How do you do?
- B: How do you do?
Chào hỏi tình huống trang trọng
- A: How do you do?

You should note that the question How do you do? does not actually require a detailed answer about someone's state or life.
Instead, it is merely a polite greeting and is often responded with the same phrase, not conveying specific emotional or personal information about someone.
2.2. When to use the structure How do you do
The structure How do you do? is typically only used in situations of first meetings or formal greetings. It is usually not used in casual conversations or when meeting friends or acquaintances,...
Instead, other greetings such as Hello, Hi, How are you?, Nice to meet you, Nice to see you again, How have you been? are used.
3. Responding to the question How do you do
To respond to the question How do you do, one would reply similarly with How do you do, because as mentioned earlier, How do you do is not used to inquire about health but as a formal greeting, similar to Hello or Hi but more formal. This phrase has become somewhat archaic and rarely appears in daily life.
In case someone asks How do you do, one can also respond with other formal greetings such as:
- Nice to meet you. (Rất vui được gặp bạn.)
- It’s a pleasure to make your acquaintance. (Rất vui được làm quen với bạn.)
- Good morning/ afternoon/ evening, I’m [Name]. (Chào buổi sáng/chiều/tối, tôi là [Tên].)

- I’m delighted to make your acquaintance. (Tôi rất vui được làm quen với bạn.)
4. Distinguishing How do you do and How are you in English
As mentioned, many English learners confuse the usage of How do you do and How are you. Mytour advises distinguishing these two phrases as follows:

4.1. How do you do?
This is not a question. It is a very formal way to say Hello. The British often use this phrase more than in the US or other English-speaking countries, and it is typically used only when meeting someone for the first time.
The correct response to How do you do? is Pleased to meet you or simply responding with How do you do. The simplest reply is Hello.
4.2. How are you?
This is a question about health, but at a casual level. Therefore, if asked and not too familiar with the asker, one should respond in a casual manner. The most common response is: I’m fine, thank you. And you? or How about you?
Other common responses to How are you? include:
Tích cực
- I’m doing well, thank you. How about you? (Tôi vẫn ổn, cảm ơn bạn. Còn bạn thì sao?)
