Some challenges in life can only be overcome through one's own efforts. But it never hurts to have a bit of luck.
At least that's how students facing high school and university entrance examinations feel around this time of year as they prepare for tests that could set the course of their lives.
On these occasions, many entrance exam hopefuls and their families visit shrines and temples to pray and pick up a good luck charm, hoping it will help them get into the school of their choice.
