How do you say hello my name is in Chinese?

There are several ways to say "hello, my name is" in Chinese, depending on the context and formality. Here are a few options:

Formal:

* 您好，我叫... (Nín hǎo, wǒ jiào...) - This is the most formal and polite way to introduce yourself. It literally translates to "Hello, I am called..."

* 请问，我叫... (Qǐngwèn, wǒ jiào...) - This means "Excuse me, my name is...". It is a little less formal than the first option but still polite.

Informal:

* 你好，我叫... (Nǐ hǎo, wǒ jiào...) - This is a casual and friendly way to introduce yourself. It means "Hello, my name is...".

* 大家好，我叫... (Dàjiā hǎo, wǒ jiào...) - This is used when greeting a group of people. It means "Hello everyone, my name is...".

After you say your name, you can add a question like:

* 你叫什么名字？ (Nǐ jiào shénme míngzi?) - What is your name?

* 您贵姓？ (Nín guì xìng?) - What is your surname? (This is more formal and is used for older people or people you don't know well)

Remember to use the appropriate tone of voice and body language depending on the context and the person you're talking to.
