How to obtain Chinese Input/pinyin

The reason for understanding this problem is that in AutoComplete we want to capture the Pinyin input by the user in advance, so that we can provide frequently-used options as early as possible so that users can enter as few as possible, find the corresponding options as soon as possible.

The first thing that comes to mind is the keyup, keydown, keypress, and input events to see which events can be captured when users input pinyin. I searched the internet and the final solution was:

Capture keyup events
