In the 24th year of Guangxu reign of Qing Dynasty, Ma Jingshan, the county magistrate, was proficient in small sugar technology, and managed the "Jixiang Zhai" Guo Jing store in Wujiachang to create crisp sugar. Because of the same surname as Ma Yuan, a famous soldier in the later Han Dynasty, it was named "Fu Bo Brand" Crisp Sugar. Later, Li Tuqi of Wujiachang opened "Kuichengnuo". Jingguo shop is an imitation, and it is named "Laojun brand" crisp candy. These two products won the "First Crispy Sugar Founding Company" of Sichuan Industry Promotion Association in 23 and 32 years of the Republic of China and the gold medal of local famous products respectively. Since then, crisp candy has become famous and its sales volume has been expanding. Later, the "Fengchixuan" Jingguo Shop in Yufu Town hired Ma Jingshan's son as a technician to produce crisp candy. Then "Shou Kang Village" and other Guo Jing shops were copied one after another. The annual output of crisp sugar in this county is about10,000 boxes.
