In 1918, the Shandong Provincial Department of Industry allocated a special fund of 40810 yuan to build a silk company on the foundation of the ancient Qingzhou government office. In August, Qingzhou Silk company was officially opened. At that time, there were 3 mulberry gardens with an area of 160 acres; there were two departments for silkworm rearing and silk production. The sericulture department specialized in producing silkworm eggs and cultivating mulberry seedlings. It cultivated more than 60,000 mulberry seedlings and produced more than 5,000 silkworm eggs every year.
