In May p>1923, shortly after the establishment of the Trademark Office of the Ministry of Agriculture and Commerce of Beiyang Government, Wuxi Maoxin Flour Factory of Jiangsu Province took the lead in applying for trademark registration with the Trademark Office, and used legal means to protect its prestigious "Bing Chuan" brand trademark, which had been used since 191. The "warship" brand has also become the first trademark registered in accordance with the Trademark Law promulgated at that time.

The main pattern of the trademark "Bingchuan" is a warship sailing to the west, which not only reflects the ideal of national capitalists at that time to actively learn from the west, accept new things and enrich the country and strengthen the people; At the same time, it also contains the meaning of smooth sailing in China culture. Trademarks are divided into four colors: green, red, blue and black to distinguish the grades of different products. At that time, color printing was not possible, and color trademarks were all woodcut plates, which had to be printed by color separation for many times, with clear patterns. The trademark was awarded the honorary prize at the Philadelphia Trademark Fair in 1926.

China's famous industrialists in modern times, Rong Zongjing and Rong Desheng, are the brothers who deal in "Bing Chuan" brand flour. After the Rong brothers founded Wuxi Maoxin Flour Company in 193, they began to use the "Warship" brand trademark in 191. At that time, there was a story that "an old car was defeated by an enemy ship" on the beach: at that time, "Bing Ship" brand flour entered the Shanghai market, and soon defeated an old brand flour in Shanghai that had been basically controlled by foreign businessmen, and "Bing Ship" became a representative of a national brand that sold well at home and abroad and showed the aspirations of Chinese people. From 19 to 1921, Rongshi Maoxin Flour Company developed from a flour mill to 12 branches, distributed in Wuxi, Shanghai, Hankou, Jinan and other places, from the coast to the mainland. Since then, the output of "Bingchuan" brand flour has accounted for more than 3% of the national Chinese flour mills. Over the past half century, the trademark "Warship" has a long history and is still popular in the new economic situation, and its historical mission did not end until 23.

The "Warship" brand not only pioneered the domestic brands, but also epitomized the industrialists' "building the country by business" and "saving the country by industry" in the Republic of China.
