Nǐ hǎo ma?

How are you?

你好吗？or 'Nǐ hǎo ma?' is a common way to greet someone in Chinese, especially those you are familiar with. It directly translates to 'you good?' or 'are you well?'. You can use it in both formal and informal situations, similar to 'how are you?' in English. But keep in mind, in China, this question is more often used when the asker really wants to know about the other person's well-being, not as a casual greeting like in English.
