It seems that quite a few students come by for luck before testing.
A good luck charm is this stork on top of a turtle.
It is very lucky to rub the turtle so you can see that the turtle's head has had some serious rubbing.There are also alters for prayers.
Inside the temple are some gold pieces - you can't rub the gold turtle since it is encased.
There was also a courtyard with these giant bonsai as we left through the gate.
