Abstract: Taihe County is located in the core area of Jitai Basin.Since ancient times,it is a developed area of food and agriculture,and this laid a solid economic foundation for the development of culture.Imperial examination and private academies took advantage of each other to promote the progressive development of culture and education.In Southern Tang Dynasty,Luo Tao founded Kuang Hill Academy in his hometown,which was a model in Jitai Basin.For the first time,people of Taihe county carried out “Patronage of Southern Palace” in the middle of Southern Song Dynasty,and gave an imitation for others.This meant a great development of social culture and education.The originality of “Patronage of Southern Palace” relied on the historical materials and was beyond question.Later,this kind of patronage based on the charitable agreement developed into“Gongshi Farm”；at the same time,the patronage to the poor became the assistance for all the participants to imperial examination,and the examination at their own expense changed to the one at the state expense.This kind of improvement of cultural and educational system contributed to the academic education and imperial examination.
