The play is based on the inventor of Juncao technology, scientist Professor "Lin Zhanhui", and focuses on how Juncao cultivation technology can be implemented abroad to help other countries get rich. At the end of the 20th century, Chinese Juncao expert Li Changhuan, under the arrangement of Fujian provincial leaders, came to the South Pacific region with Juncao technology to help the local people solve poverty problems. The conditions in the South Pacific region are difficult. Li Changhuan built mushroom sheds and other production facilities with simple means, invented dry rice technology according to local conditions, and successfully cultivated various mushrooms, which significantly improved the production and life of local people. Li Changhuan conducted in-depth research on Juncao technology. Local mushroom farmers who had a good harvest couldn't help but hold the various types of mushrooms cultivated with Juncao, singing and dancing and shouting "Chinese grass, happy grass!"
