What does mean wo shi ni hao?

"Wo shi ni hao" is grammatically incorrect in Mandarin Chinese.

Here's a breakdown:

* Wo (我) means "I"

* Shi (是) means "am/is/are"

* Ni hao (你好) means "hello"

While the intention might be to say something like "I am well" or "I am good," the correct way to express that in Mandarin would be:

* Wo hen hao (我很好) - "I am very good"

* Wo bu cuo (我不錯) - "I am okay"

* Wo shenti bu cuo (我身體不錯) - "I am feeling well" (literally, "My body is okay")

It's important to use the correct grammar and vocabulary when speaking Mandarin to ensure clear communication.
