I don’t get it.

In case you don’t either, an anonymous source explains:

The basis for this quite humorous image stems from the assumptlon that the asian character in said image has the phonetic sound of 'ching'. Hence, the cash-money symbol immediatley following said asian character (presumably a form of ancient korean of the seoul province) is meant to represent the 'cha-ching' sound which comes from cash registers being opened. Hence, asian symbols = cash money.
