Due to the use of the original Maoxin "Green Ship" trademark and Wang Yuqing's ability to sell fans, the company made a profit of 32,000 yuan in the first year. At this time, Wang Yaochen also resigned from his position as a flour seller in Huaxing Flour Factory and came to Fuxin to take over as the manager of Fuxin No. 1 Factory. Later, during the First World War, flour sales were booming, and Fuxin Flour Mill expanded rapidly. By the 9th year of the Republic of China, Fuxin had developed to 8 factories. Among them, Fuxin No. 7 Factory is the largest, with a daily output of 14,000 bags of flour. Wang Yuqing served as manager of Fuxin Flour Company and deputy manager of Fuxin No. 7 Factory. Wang Yaochen has been serving as the manager of Fuxin Factory No. 1 and Factory No. 3, and the resident manager of Fuxin Factory No. 7. Wang Yuqing is smart, capable and good at management. The two brothers respect and give in to each other and cooperate seamlessly. In the 9th year of the Republic of China, Wang Yuqing assisted Rong Zongjing in establishing the Flour Exchange in Shanghai, and stipulated that the "Green Ship" brand flour was the market standard flour. The following year, he and Rong Zongjing founded the Huashang Gauze Exchange in Shanghai and acquired two brokerage names to handle the trading of gauze, securities and other businesses. In the 16th year of the Republic of China, he spent more than 200,000 yuan to build Liyuan Garden next to Wuli Lake in Wuxi. He also opened Yunshang Silk Cloth Store in Wuxi. In the 21st year of the Republic of China, Wang Yaochen invested 100,000 yuan to establish Kangyu Cloth Factory in Yinglongqiaoyu, Wuxi. In the 22nd year of the Republic of China, the Shenxin textile system encountered economic difficulties. Fuxin factories separated from the Mao, Fu, and Shenxin Corporations and established the Fuxin Flour Mill Corporation. Wang Yuqing appointed himself as general manager. In the 23rd year of the Republic of China, when the economy of the Shenxin system was in crisis, he served as the general manager of Maoxin, Fuxin and Zhongxin Corporation. After the Japanese invaded Shanghai, the No. 1, No. 3, and No. 6 factories of the Fuxin system were all in enemy-occupied areas and suffered heavy losses; the No. 2, No. 4, No. 7, and No. 8 factories were located in the concession and were quite profitable. In the 27th year of the Republic of China, Wang Yaochen and Wang Yuqing jointly founded the Yinfeng Wool Textile Factory in Shanghai.
