"She survived a long time in a farmer's yard."

On February 15,Anyue County"An ning shi guang·Yue du yue mei"national reading activities and Qinjiushao culture inheritance promotion series activities launch ceremony,Cai Tianxin,a professor and doctoral supervisor of the School of Mathematics at Zhejiang University,shared his impression of Zizhu Guanyin after visiting the Anyue stone carving。His post on Weibo has been read 210,000 times in the past day alone.

Why did the professor from Zhejiang University come to Anyue?"To explore the upbringing of Qin Jiushao,a mathematician in the Southern Song Dynasty."According to Cai Tianxin,Qin Jiushao excelled in astrology,rhythm,arithmetic and the science of construction，systematically summarize and develop the numerical solution of higher-order equations and the solution of first-order congruence group，created a fairly complete"positive and negative prescriptions"and"great derivative seeking one"，representing the advanced level of mathematics development in China at that time,Qin Jiushao was listed as the second batch of Sichuan historical celebrities in Sichuan Province in June 2020.

"The grotto art of An Yue has influenced the aesthetics of Qin Jiushao."Cai Tianxin said that Qin Jiushao made mathematical theorems so beautiful and calculated so succinctly,perhaps because of the influence of An Yue stone carvings in his childhood,he used his life's knowledge to pursue the most beautiful realm.

On the day of the activity,the People's government of Anyue County also awarded Professor Cai Tianxin the appointment letter of Qin Jiushao Academic research Promotion consultant,and awarded the Qin Jiushao Academic Research Association of Anyue County，next,it will focus on the construction of six inheritance and development systems,namely,research and elucidation,protection and inheritance,national education,publicity and popularization,innovation and development,communication and exchange，to assist relevant departments in building cultural learning bases,planning brand cultural activities,creating fine works of literature and art,and other key work,to promote the formation of the construction of Qin Jiushao culture inheritance and innovation system.

In fact,Qin Jiushao also had a profound influence on the local people，Li Yi,the representative of"The Most beautiful Reader"in the national Reading activity of"An ning shi guang·Yue du yue mei"in Anyue County,Ziyang City,shared her reading comprehension，referring to a classic book called《Mathematical Treatise in Nine Sections》,which brought her infinite thinking and life.The author of this book is Qin Jiushao。"I have lived in Anyue since childhood,and the Jiushao culture has witnessed our growth."According to Li Yi,Qin Jiushao kept reading and learning the six arts even in his miserable days，she believed that Qin Jiushao's achievements in astrology,rhythm,arithmetic,poetry and construction could not be separated from his extensive reading and deep study,and his brilliant and profound knowledge could not be separated from his love of reading.

The Southern Song Dynasty mathematician who lived in Anyue since childhood，he compiled his accumulated mathematical knowledge and research into a world-famous masterpiece called《Mathematical Treatise in Nine Sections》，he is good at inheriting and daring to innovate in the field of mathematics，Therefore,I think reading is also a kind of inheritance,inheriting history,inheriting mission,inheriting spirit and inheriting civilization.

He once said:"Jiushao is stupid,not idle in art",he kept on reading and learning the six arts even in the days of suffering，Therefore,I believe that his achievements in astrology,rhythm,arithmetic,poetry,and construction could not have been achieved without his extensive reading and intense study.I also believe that his talent and knowledge cannot be separated from his love of reading.

The unique charm of ancient Oriental mathematics and its perfect combination with the"ancient,diversified,refined,beautiful and special"stone carvings in Anyue have important research value and significance for the future generations.（Xiao zhengjun，Liu jiaxin）
