According to historical records, Qingquan Temple was founded in the 21st year of Zhenguan (648-649). In March of the 21st year of Zhenguan (647), Li Shimin of Emperor Taizong decided to take the due east route again, appointed Li Xun as the chief marching officer of Liaodong Road, led the troops to Yingzhou (Chaoyang area), and returned to southern Liaoning along the route of "Emperor Taizong's personal expedition". Also known as General Zuo Wuwei, Niu Jin, the marching general of David's clear autumn road, led his troops across the sea from Laizhou (Ye County, Shandong Province) and went straight to southern Liaoning. First of all, Niu Jinda crossed the sea from Laizhou, landed at Shizikou (Lushunkou), stood at Heifengguan (Nanguanling), fought for Yulin (Jinzhou), and passed Bolandian (Pulandian), which made him sad. The main force passed the Dayingzi (in Zhuanghe) and went straight to Long Yuan (Fengcheng County). In July, soldiers arrived in Shicheng (northeast of Fengcheng County), killing thousands of enemies. Southern Liaoning in July looks very pleasant. Why did general manager Niu Jinda return to Korea? An important reason is that there is continuous rainfall in southern Liaoning, and sometimes it rains "rain soil" (sediment), which is not suitable for war. In fact, when Niu Jinda left Yulin (at that time, Pulandian, Pikou and other places were under the jurisdiction of Yulin), it was already "lack of water and soft-hearted." He had to send "Youqi" to "find water" along the way. A "Youqi" reported that a clear spring was found in an ancient camp surrounded by mountains (mountains with gables on all sides). Niu Jin flew to Malaysia to see that he was "trapped in the Austrian grass, with springs" (springs hidden in deep grass) and "vigorous, which can satisfy hunger" (springs naturally flow out, which is sweet to quench thirst), so Niu Jin dismounted, bowed down and thanked heaven. Niu Jinda camped here and "buried butterflies for sacrifice" by the clear spring (set up a stone platform to burn incense to worship the sky). According to Niu Jinda's marching route and the time at that time, this mountain city surrounded by mountains is now Weiba Mountain City.
