Shu-Yuan, a kind of private schools supervised by scholars, played an important role during the period of traditional education in China. There are four important Li-xue scholars, whose learning devoted to the study of classics with a national approach, lectured in the Shu-yuan during the South Sung Dynasty : Chu- huei-an, Liu-hsiang-shan, Lu-chiu-yuan and Chang-ran-hsuan. They had grat name at that time, proposing many outstanding ideas on education and set a modal in educating the succeeding generations. Chu-huei-an, born in Fukien, was a prodigy in early childhood. At the age of 19, he was listed as Jin-shi, examination, and then was assigned as complier in the Privy Council. However, he was impeached several times for being categorized as an advocate for the "False classics". Chu reluitlt the Bai-lu-tung (White Deer Cave) school, and established the school regulation. As a productive academic writer, Chu possessed a high academic status in China. "As Confucius is to Chou Dynasty, so Chu-huei-an to the Sung Dynasty, and from both cases came great man that summed up the modals of an ruce", said Tzai-yuan- pai. Chu thought that the heighest aim of education was to cultivate saints, that is, to develop a sound and perfect character. Liu-hsiang-shan, born in Kiang-si, grew up in a family with academic atmosphere. The six brothers in the Liu family learned from one another by exchanging their views, which brought about a very close and harmonious fraternity. Liu was in the same era as Chu-shi, with whom he has a friendly relationship despite differences in ideas - Liu thought that the aim of education was to teach people "becoming a human being", which means a person should not lose his conscience, and then became a great man who could be described by Mencius as someone who "doesn't lose his natural kindness". Lu-tung-lai came from Chekiang. As descendants of Lu-gang-zhu, the Lu family have been pure Confucians. Out of the elites, the Lu's were benefited from the classics of the Central plain. Lu, Chu-huei-an and Cheng-nan-hsuan were good friends with each other, and the relationship was helpful in Liu's academical achievement. Liu's specialty was in History, not in Li-xue. He had served in the imperial coust for 20 years, mainly denoted himself to affairs concerning history, and spent his spare time in lecturing. Lu had presided over the "Li-Ze" school for 8 or 9 years and made "Lu's school regulations", which come before the "White-Deer-Cave regulations" and was more considerate on the daily-life. Lu stressed that the school could serve the function of social education. Therefore his aim in education were mainly "flourishing confuciunism" and "transforming customs". Chang-nan-hsuan was born in Hu-nan. His father, Chang-jun, was a famous official in the South Sung Dynasty. Chang once participated in his father's office, learning the post after his father died, but then served as a magistrate of fu and Yien Province. He then presided over the Yu-Lu school where Chu-shi also came his lectures that made the studying atmosphere there prosperous. He thought people to "study from fundamentals", saying that we should "progress gradually" and "to investigate things and to extend knowledge to the utmost". Hence his education principles concentrated on investigating and extending the knowledge, and acting with might. Those four famous scholars mentioned above not only had great academical accomplishments, their spirit in patiently guiding and teaching people was especially admirable. Therefore what they had done set a perfect modal for those who denote themselves to education nowadays to follow suit.
