题
Ti2 theme topic is To Be + the image of a persons face. To be is abstract 是 is composed of the solar disk ri 日 on top of the word for upright 正 which in turn is composed of 1 一 yi1 and stop 止 zhi3.
To be is the abstract idea of a person stopped standing upright underneath the sun. But if you put another persons face 页 ye4 in the picture it turns into a dialogue of two people talking beneath the sun and thus becomes THEME TOPIC.
页 alone in modernity means a page of paper, a sheet of paper but it originally is a picture of a persons face (chopstick in the hair on top square is the outline of the head and the two lines are their eyes). When 页 is used alone it is a piece of paper, a page; but when used as a character component like in 问题 it still means face.
