Laoma, known as "Laomaqu" in ancient times. It is said that Emperor Zhaolie of the Han Dynasty Liu Bei stationed troops in the Bajiao Temple and Liu Zhang were separated, and Liu Zhang decided Fujiang flooded Liu Bei's army, Zhang Fei led his troops to retreat through this place. Because the water was so strong that his horse could not cross the canal, Zhang Fei was impatient and his horse could not cross the canal. Later generations called this place "Laomaqu", and gradually a settlement was formed and a market was established. At the end of 2019, Santai County merged its townships and towns, merging the three towns of Laoma, Mileage and Guanghui to establish a new Laoma Town, with the town’s headquarters being Laomaqu.
At the end of the Qing Dynasty and the beginning of the Republic of China, No. 28 Township was established in Santai County, and Laomaqu was the residence of Fangri Township on the East Road; Guanghui was called Huilongchang at that time, and it was under the jurisdiction of Zhenshui Township on the North Road (in Gaoyankan, today Gaoyan Township).
