During the war years, she created a legend with a cup of black tea. In 1938, smoke filled the air. Feng Nuoning, who returned from overseas studies, was hit by the sudden death of his father before he could realize his ambitions, leaving only the precarious Shunning tea factory. There are foreign companies that monopolize prices and lower prices, warlords that impose exorbitant taxes and miscellaneous taxes, and military commissioners who are like wolves. The label of "communist" can make a person doomed. Faced with the desperate situation of being coveted by a pack of wolves and the tea factory in danger, this delicate and delicate woman resolutely tied up her long hair and stepped into the workshop. She vowed to keep her family business and use this piece of oriental leaf to exchange for life-saving guns for the broken mountains and rivers. The road to industry is full of thorns every step of the way. She teamed up with Lu Zheng, a mysterious technician with superb skills, to break through many technical barriers and make "Shunning Red" frightening. She mediates between the greedy tea merchant president, the violent warlord's adjutant and the ruthless military commissioner, working together vertically and horizontally to find a way out in the cracks.
This is a battle related to the survival of industry, material channels and the life and death of the country. Feng Nuoning and Lu Zheng, one is a bright light who upholds the family business and ingenuity, and the other is a sharp sword lurking in the dark night to protect the light. Can they protect this red hope despite the destruction of Japanese spies, the suspicion of the Kuomintang, and the betrayal of internal moths, and let the fragrance of Yunnan Red start a prairie fire on the flames of war?
