Designer Lin Xi, tired of urban involution, returned to his hometown in a mountain village in Yunnan to inherit a tea garden. She overcame the villagers' doubts, introduced ecological planting technology, and transformed the old tea garden into an Internet celebrity base for "tea and tourism integration". In the process, she cooperated with Chen Yang, a veteran who had returned to his hometown to start a business, to build roads, build B&Bs, and promote e-commerce. However, she encountered malicious competition from bullies in the neighboring village and threats of land expropriation from developers. When the tea garden was selected as an intangible cultural heritage protection project, Lin Xi discovered that the ancient tea tree protected by his father was actually the ecological key to resisting soil erosion.
