Shuowen Xu Note: According to the Book of Changes: Peering into the door, it is qu, deserted with no one there. To peer is to look narrowly. To be wide-eyed is to open the eyes wide. It means that when one first looks narrowly, even with eyes wide open, one sees no one. The meaning should only use the character for wide-eyed.
