Once upon a time, there lived an old woman who could cook delicious red bean porridge in the mountains. In March, when the old woman was busy weeding, a ferocious tiger suddenly rushed out, baring its teeth and wanting to eat her. The grandmother begged the tiger to wait until the red beans were harvested and eat her after drinking the red bean porridge. The tiger agreed to wait until winter. But the first day of the new year, but the fifteenth day, the snowy winter finally came, the old woman sobbed sadly, and didn't know what to do... At this time, chestnuts, turtles, stretchers, and pointed awls appeared one by one. , they all say that they have a way to subdue the big tiger, as long as they can drink a bowl of the old woman's delicious red bean porridge. "Snoring, babbling", after drinking the red bean porridge, they hid and waited for the tiger to appear. "Bang bang bang", there was a broken gong, and a tiger's voice came from outside the door, "Ow—old lady, bring me the delicious red bean porridge, grind your teeth first, and you will be more agile to eat later." Will the old woman finally be able to save herself from danger...?
