In the Great Cultural Revolution of the proletariat, the vast numbers of staff and workers of Feixi County Nursery in Anhui Province have eradicated superstition and emancipated their minds. Since 1967, the experiment of whole seedling nursery of Chinese fir has been succeeded in 1970, reducing the cost of raising seedlings by more than 50%.
