How can I use the smart keyboard for iPad air pro to write Chinese?

Thank you. It is overtaken by event. I found that I did not set the accessibility to the smart keyboard. So, I went to setting , accessibility, keyboard, full Key Board Access, and turn it on.

It is now all connected. I press the earth logo on the keyboard and select whatever Chinese input on the screen that I want.

Thank you for asking. As you said, no problem at all. Apple is very user friendly in hand writing Chinese characters.
