Lung cancer is one of the malignant tumors of the respiratory system, which has the fastest increase in morbidity and mortality in the past 100 years. What’s more, it threatens human health and life. The 2020 World Cancer Report states: Lung cancer is currently the leading cause of cancer deaths worldwide, accounting for about 18% of all cancer deaths [1]. The National Cancer Center released the latest issue of national cancer statistics in 2019: Lung cancer is at the head of malignant tumor in China in terms of incidence (20.03%) and mortality (26.99%). Some Chinese medicines have good effects on inhibiting the growth and spread of cancer cells, and can significantly improve symptoms and patients’ quality of life in the treatment of lung cancer. Pattern of qi stagnation and blood stasis is one of the basic patterns of lung cancer patients, so the treatment of boosting qi and quickening the blood occupies an important position in the treatment of lung cancer[2].Professor Feng Yuan believes that the onset of lung cancer is the root vacuity and tip repletion, root based on qi vacuity and tip is the result of mutual influence of phlegm turbidity and depressed accumulation of static blood. Due to the long-term disease, the formation of the accumulation eventually leads to the formation of cancer. He pays special attention to in treatment, at the same time, combines with clinical practice and regards them  as the basis for determining treatment. Consequently, he innovatively proposed to treat lung cancer of pattern qi vacuity with blood stasis by supplementing lung qi and quickening the blood and transform stasis.
