A clap of thunder heralds the arrival of spring, and the pure, fresh air of the mountains brings forth the most exquisite bamboo shoots. Seeking this delicacy, farmers toil in the fields, yet the sweetness of the harvest is fleeting, and the freshness is difficult to preserve, making them cheap to sell. Lamenting that the fresh, wild flavors are not readily available to the public, and that seasonal delicacies are fleeting, and that farmers toil so hard yet struggle to earn even a pittance, Yi Kuixin, the founder of the Gengshengtang brand and a 140th-generation descendant of Yi Yin, the famous prime minister of the Shang Dynasty, is carrying on his ancestral aspirations to seek the true flavor of bamboo shoots and bring them to a wider market. He uses the "inheritance of Yi Yin's ancient medical and culinary recipes" to embark on a "big dream for small bamboo shoots," referencing classic texts such as "The Theory of Five Flavors and the Theory of Cooking Time" and "The Classic of Decoctions," and annotating and innovating upon them to develop the "Yi's Biological Preservation Method" and the Thunderclap Bamboo Shoots.
