How do you WRITE hello how are in Chinese?

You can't directly translate "hello how are" into Chinese. You need to include "you" to make it grammatically correct.

Here are some ways to say "Hello, how are you?" in Chinese:

Formal:

* 你好吗？ (Nǐ hǎo ma?) This is the most common and polite way to greet someone and ask how they are.

* 您好吗？ (Nín hǎo ma?) This is even more formal and respectful, often used for older people or people in positions of authority.

Informal:

* 你好 (Nǐ hǎo) This is a simple greeting that can be used in most situations. You can add 最近怎么样？ (Zuì jìn zěnme yàng?) to the end to ask "how are you doing lately?".

* 怎么样？ (Zěnme yàng?) This is very informal and means "how are you?". It's best to use this with close friends or family.

* 最近还好吗？ (Zuì jìn hái hǎo ma?) This is a polite way to ask "how are you doing lately?".

Other options:

* 你身体怎么样？ (Nǐ shēntǐ zěnme yàng?) This literally translates to "How is your body?" and is a slightly more formal way to ask about someone's health.

* 最近工作/学习怎么样？ (Zuì jìn gōngzuò/xuéxí zěnme yàng?) This means "how is your work/study going lately?"

The best way to choose a phrase depends on the context and your relationship with the person you are talking to.
