In the Buddhist tradition, Foo dogs (or lions) guard the entrance to the temple.
History:
The Chinese Foo Dog (fu is the Chinese word for happiness), also known as the Happiness Dog as well as the Celestial Dog, originated in China with its name deriving from the city of Foochow.
It traces its ancestry back over 3000 years.

Foo Dog or `Lion of Corea'
Foo dogs are really lions.
Behind their aesthetic appeal is a rich history of legend and tradition.
The lion is known as the proud mater of the feline race.
It is not indigenous to China in recent years, although lion artwork and sculptures were imported gifts to the emperor.
The lion does not occur in Chinese primitive art, but was introduced later in connection with Buddhism as the defender of law and protector of sacred buildings.
Lions are often placed at temple gates and porticos of houses.
Sometimes, they guard tombs.
Stone lions in front of official buildings were originally put there to scare demons.
The conventional Chinese lion is sometimes called the "Lion of Corea" or the "Dog of Foo,"
because it was found at the threshold of Buddhist temples.
The lion is sacred to Buddhism and is sometimes presented as offerings to Buddha.
Some Buddhist deities are occasionally depicted mounted on this beast.
It is an emblem of value and energy, those indispensable complements of wisdom, and was embroidered on the court robes of military officials of the second grade.

The sign reads:
Sculpted in the Ming Dynasty (1368 - 1644 AD), and well over 2 meters height,
These Fu Dogs are the first large Fudogs south of the Changjiang River.
The Male Lion is playing with a silk ball.
The Female Fu dog is playing with her cub.
All Charmingly naive and lifelike.
They are quite unique in Buddhist Temples.
