In the southern suburbs of Qingping Town, there lived a family that made biscuits. The head of the household was Old Man Wang. His wife passed away early, and Wang Wen and Wang Wu had two sons under his knees. Old Man Wang felt he didn't have much time, so he wanted to separate the families of his two sons. Wang Wen was shrewd and tyrannical and grabbed the biscuit shop and the three big houses in the old courtyard, while Wang Wu only got two broken houses in the wasteland.

Not long after Old Man Wang died of illness, Wang Wen got into the business of the biscuit shop, and his life was okay, while Wang Wu painstakingly cultivated his one-and-a-third mu of land, and his life was very difficult. When the swallows came out in autumn, they flew north, and Wang Wu lived in a nest of little swallows under the eaves. Wang Wen watched the little swallows build a nest to feed while farming, which was very interesting.

One day when Wang Wu came back from farming, he saw a little swallow lying on the ground with its wings flickering and unable to fly. When he walked in, he found that it was the little swallow that had fallen from the nest. The big swallow was chirping next to the bird's nest, and Wang Wu gently held the little swallow in his hand, smeared some medicine on his injured wings, and then caught a few earthworms to feed him. After a few days, the little swallow could flap its wings freely, and Wang Wu took the ladder and put the little swallow back into the nest. The little swallows inside seemed to welcome the return of the brothers and sisters, while the big swallow stroked Wang Wu's hand and rubbed it back and forth with his mouth, as if to express his gratitude.

Wang Wu was drinking tea in his yard that day when he saw Big Swallow landing on the tea table with a grain of rice in his mouth. However, this grain of rice was golden, which Wang Wu had never seen before. Big Swallow put the grain of rice in Wang Wu's hand, chirped a few times and flew away. Wang Wu felt very interesting, so he buried the grain of rice in a pile of soil in the corner of the wall. Because it was a busy farming season, Wang Wu only cared about working hard in the fields, and the little swallows also flew to the south. After a long time, Wang Wu saw rice growing in the corner of the wall, and the huge ears bent the branches, shining with golden light. Wang Wu then remembered the grain of rice he had buried before.

Wang Wu went forward to peel off the ears of rice and was startled. This is not a grain of rice, but a small golden bean. Wang Wu counted more than 200, and the scale was as much as a catty. Wang Wu was overjoyed.

When Wang Wen heard that his brother had made a windfall, he and Wang Wu asked how he had made his fortune. Wang Wen was an honest person, and he had no heart for his brother, so he told him how to save Xiaoyanzi, and then how Xiaoyanzi gave rice grains. Finally, Wang Wen went back and didn't have the heart to make biscuits to earn the hard money. He looked at the trees in the courtyard all day, hoping that when the trees would sprout, it would be easy to save the swallows and make a windfall after spring came. Waiting time was like a fire roasting, and Wang Wen simply soaked in the tavern every day to drink and eat meat, thinking that when I made a windfall next year, what would this money be?

Winter and spring came, and Wang Wen basically ran out of money, and spring finally arrived. Wang Wen was looking forward to Wang Wen finally waiting for the swallow to nest under the eaves of his house and give birth to a nest of small swallows. But Wang Wen stared at the little swallow every day, and he just didn't fall out of the nest. Wang Wen thought to himself, how could he save the little swallow if he didn't fall? If he didn't save it, he wouldn't give him golden rice grains. Wang Wen's mind turned around, and when the big swallow went out to forage, he took out a small swallow from the nest and broke the little swallow's wings with force. When the big swallow came back, Wang Wen pretended to help the little swallow apply medicine and feed the earthworms, just like what Wang Wu said. Sure enough, the big swallow also brought a golden rice grain to Wang Wen, and Wang Wen happily planted the golden rice grain into the delicate flower pot.

After a long time, the swallow flew away, and Wang Wen ran out of money in his pocket. The only thing he did every day was to keep watering the golden rice grains. Seeing that the rice in the ground had been harvested, Wang Wen's golden rice grains had not yet sprouted.

Wang Wu's big goose was bitten to death by a dog, so he stewed the goose, and Wang Wu took a bowl for his brother to eat. Pushing open the door and seeing his brother lying on the ground, he was out of breath, Wang Wu cried to death, and the neighbors helped bury Wang Wen. Finally, Wang Wen's house and Old Man Wang's biscuit shop were picked up again by Wang Wu, and his life was stable and happy.
