Vegetables are all grown from seeds. "Plant a millet in spring and harvest 10,000 seeds in autumn". Through the story of Niu Changcun growing vegetables and opening a vegetable shop, we know that all the vegetables we eat are planted with seeds, and we also know that nature is endless and prolific. As long as you work quietly in the right season, there will always be a harvest day, and the sweat you pay will be rewarded with a bumper harvest.
