The earliest cement plant in China is 1889. Li Hongzhang, the Qing government, approved Tang, general manager of Kaiping Mining Bureau, to set up a cement plant in Tangshan, named "Tangshan Fine Cotton and Soil Plant", which was completed and put into operation on 1892. 1906, Yuan Shikai, Minister of Beiyang, ordered Zhou Congying to re-do it and renamed Qixin Lime Company. 1907, Tangshan Fine Miantu Factory was renamed as "Tangshan Qixin Lime Co., Ltd.". The cement trademark is designated as "Longma Negative Taiji Map" brand (commonly known as "continental brand"). Mapai Cement is the earliest brand in China.
