How do you say hello how are in mandarin?

Here are a few ways to say "hello, how are you?" in Mandarin, with explanations of formality and context:

Formal:

* 您好，您最近好吗？ (Nín hǎo, nín zuìjìn hǎo ma?) - This is the most polite and formal way to greet someone and ask how they are. It is suitable for elders, people in positions of authority, and strangers.

* 您好，您最近怎么样？ (Nín hǎo, nín zuìjìn zěnmeyàng?) - Similar to the above, this is also very formal and polite.

Informal:

* 你好，最近怎么样？ (Nǐ hǎo, zuìjìn zěnmeyàng?) - This is a more casual greeting and suitable for friends and acquaintances.

* 你好，最近还好吗？ (Nǐ hǎo, zuìjìn hái hǎo ma?) - This is a slightly less formal version of the previous option.

Other ways to ask "how are you?":

* 你最近好吗？ (Nǐ zuìjìn hǎo ma?) - This is a direct way to ask "how are you?" and is suitable for friends and family.

* 最近怎么样？ (Zuìjìn zěnmeyàng?) - This is a casual way to ask "how are you?" and is appropriate with people you know well.

Things to keep in mind:

* When greeting someone, always use "您好" (Nín hǎo) if you're unsure of the appropriate level of formality.

* The word "您" (Nín) is a respectful form of "你" (Nǐ) and should be used when addressing someone older than you or in a position of authority.

Remember that these are just a few examples, and the best way to say "hello, how are you?" in Mandarin will depend on the specific context and your relationship with the person you are talking to.
