ABSTRACT
Literally, means ‘above sea’; means ‘extensive region’ as the character (zhdu) is an old name for an administrative region and means ‘deep ditch in the field’ as it used to be a large paddy field.
Let us now look at the following two characters that appeared in Dialogue 2:
huàn to change kàn to see
To change things, you need your hand, hence the hand head component (z); and to see things, you put your hand over your eyes (imagine you are trying to see something in the distance under the bright sun!).
