The predecessor of Naaisi was the local state-owned Lishui Wuqi Chemical Factory, which was established in 1968 and is currently the world's largest detergent production base. Naaisi Group has strong technical force, has a number of independent intellectual property rights and patents, and wholly acquired the century-old Runfa, Oni and other brands of British China Lion Company. Diaopai soap is also a strong old brand, with a strong decontamination effect, but it is mild and has no protective effect on the skin. Diaopai laundry soap has won a number of domestic awards, and participated in the formulation of national product standards. But the brand is positioned in the low-to-mid-range.
