In the troubled times at the end of the Southern Song Dynasty, Wen Yang, a local official in Bozhou, sent elite troops for many times to rescue various important places and moved to the south and north of Sichuan, which made great contributions to the Southern Song Dynasty. As early as the 11th year of Yujie and Chunyou (125 1), Wen Yang sent Zhao Yin, a general, to lead the elite troops out of Bozhou, meet the main force of Yujie's Northern Expedition in Chongqing and March into Hanzhong occupied by Mengyuan. In the second year after the failure of the Northern Expedition, the Mongolian army seized the opportunity to besiege Jiading (now Leshan, Sichuan), an important town in the Southern Song Dynasty, and Yu Jie dispatched troops from all over Sichuan to help.

Wen Yang also sent general Tian Wan to lead 5,000 Bozhou soldiers to Jiading from the path, which contributed to Jiading's clearance. It is precisely because of these achievements that Song Ting upgraded Xiong Weijun of Bozhou to the "imperial army" and expanded it into the Fifth Army, giving local officials and fans the status of the Song Ting Central Army for the first time. In the second year of Bao You (1254), the Mongolian army of Yunnan left Wumeng (now Zhaotong, Yunnan) in the north, crossed the Jinsha River and went south along the river, threatening Chongqing, the capital of Sichuan in the Southern Song Dynasty.

At that time, Zengbo Li, the special envoy of Sichuan Anfu and Jinghu, recruited Song Jun to help Chongqing, including Bozhou Army. Pai Di Sheng rode 5,000 soldiers out of Bozhou to join the Southern Song Dynasty army in intercepting the North and South Mongolian armies and besieging Chongqing. In the second and sixth year of Bao You (1258), Mongolian Khan Mongo led the Mongolian army into Shu, and even joined most counties and counties in Sichuan in the Southern Song Dynasty to besiege Chongqing Barrier Fishing City. Sichuan was in a critical situation.

In this case, Pu Zezhi, the special envoy of Sichuan appeasement, recruited a state army to defend Chongqing with Song Jun and help Fishing City. Another part of Bozhou Army was ordered to go south to Wujiang River to contain the Mongolian army occupying Fucheng House (now Fuling, Chongqing), and to cooperate with Song Jun to reinforce the river and break through the blockade of the Yangtze River by the Mongolian army. After Wen Yang was besieged in Fishing City, he was "added as the permanent ambassador of Zhongzhou" by Song Ting. During the Ding Jing period (1260 ~ 1264), Liu Zheng, the commander of Luzhou, surrendered to Mengyuan, and the Mongolian army besieged Etiquette City (now north of Quxian County, Sichuan Province) and Daliang City (now Guang 'an, Sichuan Province).

And the construction of Panlongcheng threatened Kuizhou (now Fengjie East, Chongqing), and the situation in Sichuan deteriorated. In this situation, Liu and Xia Gui, the envoys of Sichuan appeasement, successively called on the broadcasting national army to take part in the battles of recovering Jiang 'anzhai (now Jiang 'an County, Sichuan Province), escorting the grain and grass supply city and besieging Hu Xiaoshan, the Mongolian army. Because of this series of military exploits, Wen Yang was promoted to "Doctor Jin Zhongliang, State Defense Envoy, State Peace Envoy, and Jue Bozhou Bo", reaching the peak of his career.

In the first year of Song Xianchun (1265), Wen Yang died, and Song Ting "offered an observer in Jinzhou" and "chased the seal and broadcast the frenzy". Wen Yang's descendants buried him in Weishan Plain, Gaoping, Huichuan District, Zunyi City, and erected a tombstone of Wen Yang with a long inscription on it. After the demise of the Southern Song Dynasty and the return of Bozhou to Yuan Dynasty, Wen Yang's descendants did not want to erect a stone tablet in front of Wen Yang's tomb, so they quietly removed it and buried it in front of Wen Yang's tomb. This important stone tablet was excavated by archaeologists and became the physical witness of Bozhou local officials and the history of the Song-Mongolian war at the end of the Song Dynasty.
