A down-and-out college student was fishing by the stream, and occasionally got the token of the Qing Emperor's inheritance. Since then, he has leaped into the dragon's gate and lived happily ever after. With a little yellow dog, he went up the mountain to collect medicine, went down the river to catch fish, planted flowers and raised bees, hunted in the mountains, and tamed rare birds and animals, leading the villagers to make a fortune and build Taoyuan Mountain Village.
