Fei Xiaotong’s(Fei Hsiao-tung)works on rural economies and societies written in the 1940s were deeply affected by British economic historian R.H.Tawney.Through comparison,this article reveals at least two connections between their works.First,Tawney’s analysis of the transition from agricultural modernization to industrial modernization in Britain serves as a reference for Fei’s works on the economic transformation of the Yangtze Valley in Jiangsu and Lucun village in Yunnan.Second,Tawney’s“theory of gentry”also serves as the underlying view for Fei’s theory on the functions of the Chinese gentry.However,Fei does not simply follow Tawney’s steps.Instead,he offers unique insights into the issues of horticulture transformation and gentry types in China.Furthermore,in Fei’s social theory and practice,the role of“state”was considered to be less positive.The interrelations of the community,market,intellectuals and the state construct Fei’s modernization scheme of China.His idea about how China,a slower participant in the world system,can maintain economic autonomy was still valuable today. 展开更多

Han Fei presented a thought-provoking perspective on human nature and its implications for governance.Departing from traditional moral doctrines,Han Fei’s“non-moralistic”philosophy posited that human nature is inherently self-interested and driven by personal gain.In this paper,we explore Han Fei’s keen insights into human nature and its practical application in political governance.His emphasis on aligning political strategies with human inclinations,rather than relying solely on moral preaching,highlights the complexity and pragmatism of his approach.However,we also examine the limitations of his philosophy,particularly in disregarding individual differences and idealism.By striking a balance between political expediency and moral considerations,Han Fei’s ideas continue to resonate with contemporary discussions on governance and human behavior.This study calls for a reflective and cautious assessment of the implications of Han Fei’s“non-moralistic”thought in today’s society. 展开更多

As a national cultural property,General Zhang Fei’s Temple is the largest ancient architectural complex in the Three Gorges of the Yangtze River.It was built in the Han Dynasty and has a long history of nearly 2,000 years.In 1994,the Chinese government launched the Three Gorges Dam project at the Yangtze River and implemented the largest relocation project for the General Zhang Fei Temple to prevent it from being submerged.The temple was relocated 32 kilometers upstream along with the local people of Yunyang County,and the historic environment was rebuilt on the opposite side of the migrant city of New Yunyang County.The temple was restored successfully and the tradition of offering sacrifices to General Zhang Fei continued in the local community.The relocation project lasted for 8 years and became the largest cultural heritage conservation project of the People’s Republic of China at the end of the 20th century.This paper comprehensively summarizes and reviews the project goals,implementation process,and project highlights of this relocation,so as to provide an important case reference for heritage conservation projects in the future. 展开更多

Background: Scientific procedures for addressing noseband fit and tightness, eliminating the risk of excessive and painful tightening, as well as quantitative measurements of pressures under the noseband while riding are either scarce or lacking. Purpose/Aim: To assess simple means of measuring pressure under different nosebands with a view to their adoption as scientific methodology. Method: Horses (n = 7) were fitted with five different bridles (A-E). Pressure distribution and intensity were measured using colour sensitive film (Fujifilm LLLW), assessing the level of pressure and distribution across the surface of the nosebands, as assessed and ranked by independent assessors. A CURO system was also used to measure pressure in real-time under nosebands whilst riding. Results: The colour-sensitive film for D & B were ranked 1st and 2nd, respectively. Regularity of pressure overall showed a statistical difference between nosebands (A & B significantly more unregular than the others). Pressure measurements revealed significantly different means (all P Conclusions: Pressures under nosebands can reach levels that appear capable of inflicting tissue damage, hence bridles and nosebands should be assessed using scientific methodology and not based on arbitrary and subjective criteria, as is currently the case. 展开更多
