Changhe originally pursued the county magistrate, promoting learning for the people and benefiting future generations. 1904, Miao Runlong, a poet and magistrate of Yangxin County in the late Qing Dynasty, resolutely innovated and founded Yangxin Official School.

Miao Runlong (185 1- 1939), formerly known as Yu Long, Manchu, Zhengbaiqi, Han army, word Lindong, cold fisherman, Shenyang. In the first year of Guangxu (1875), Juren was a scholar of Renchenke in the eighteenth year of Guangxu (1892), and was awarded editing by imperial academy. He used to be the director of the household department, and 1903 (the 29th year of Guangxu) was awarded the alternate magistrate and magistrate of Zhili Prefecture in Linqing County, Shandong Province. Miao Runlong was born in a scholarly family, and his great-grandfather was Miao Gongen, a famous scholar in Shengjing during the reign of Kanggan. "How much to stay in the capital, always let the public lead." 1904, the Qing government carried out the "New Deal" and "abandoned private schools to promote learning". Miao Runlong enthusiastically encouraged him to establish a "second-class primary school hall for senior high schools" in the former site of Yongning Temple in Yangxin County and a "Langqiu public school" in Wolf Hill in River Tofu Shop, and wrote a stone tablet for the former, which has been preserved to this day. The nature of these two schools is different from the "private schools" and "academies" in the past, and they are government-run schools. In particular, Yangxin official school, with a "normal college" attached, implements the class teaching system, which is the embryonic form of Yangxin modern education system. In the following hundred years, "Yangxin Official School" gradually evolved into Yangxin No.1 Middle School, and two famous local schools, Boxing Normal School (195 1 July) and Yangxin Experimental Middle School (1September 992), were born.

In the past hundred years, Yangxin No.1 Middle School, together with its peers in the century, has sent a batch of outstanding talents to famous universities in China, such as Peking University and Tsinghua University, and more than 40,000 graduates have left the school successively, making outstanding contributions to the struggle for national independence, socialist revolution and construction.
