I graduated from the former Hsiang Ya Medical College (a Yale-affdiated medical school in China before Liberation in 1949, and the predecessor of today’s Hunan Medical University) in 1952. My aspiration to be a clinical doctor was strongly influenced by my father Sophie (his pen name) whereas my devotion for all my life to neuro-anatomy resulted from the interaction between the mandatory system of work assignment by the State and my personal selfdevelopment. In the year of my graduation, the Ministry of Public Health under the National Military Commission was in need of a human anatomy lecturer and asked its civil counterpart to select a nominee for the vacancy. At the time, Ihad chosen basic medical research as my career and anatomy was definitely not one of my options, nor was any of my classmates in favor of it.

Forests are threatened by a lot of dangers and all of us have to contribute to the fight for their survival. The methodology of school research on pine woods which is described below, aims to cultivate more sensitive, educated and activated students, by accordingly specialized teachers who are going to organize the educational background, also to decide techniques and materials for the easiest and most effective learning, for the cultivation of values, attitudes and friendly behaviors towards forests. The suggested methodology is based on the findings of a European Comenius Program and two Programs of Environmental Education. The research usually takes place in a pine land, by using a worksheet as experimental tool, and focuses on the vitality of the trees, the biodiversity, the effects of pollution and other cultural elements related to the pine bio-community. There is also a lot of informative discussion and research over cultural, social and economical factors with locals and specialists.展开更多
