I've got two horizontal lists - one that contains Chinese characters (list A) and the second that contains the decomposition of the selected character (list B). Currently, when the user clicks on either a Chinese character or a component, it will be displayed in the big box above.

Clicking on an item in list A would display related information in list B?
Clicking on an item in list A or B would display more information in the big box?
I think I looked at this for too long and can't quite think of a way to improve it, so any suggestion would be appreciated. Here's the current UI:
