In China Maitreya is known
as "the laughing Buddha" and is usually represented as a rotund
figure with a happy disposition. His Chinese name is Pu-tai
Ho-shang or "Hemp-bag monk". He is originally a fertility figure
who was known to bring "goodies" in his bag to local townsfolk,
especially children. Later, he became a pre-incarnation of
Maitreya. In Japan he is called Hotei and is one of the seven lucky
gods.
Most people encounter this
figure in Chinese shops and restaurants and confuse him for the
historical Buddha Shakyamuni. The common tradition is to rub his
belly for good luck and prosperity, this is because his big figure
is a sign of abundance.
