A Complex Chinese Character
This is actually not one character, but a stylistic conglomeration of the characters in the phrase 招財進寶, meaning "ushering in wealth and prosperity".

The characters 財 and 寶 end up being represented with the same 貝 component in this "character". While the left side of 招 (扌) and the right side of 財 (才) are technically not the same component, they look similar enough to be represented with the same component here as well.
