The college students'“Sanxiaxiang” is the important form of cultivating people from practice in Chinese universities. Since the formal inauguration nationwide in 1997，the college students' social practice activities of “Sanxiaxiang” have undergone twenty-one years' development. These social practice activities have achieved marked success，attracted extensive social attention，and exerted great influence in the group of college students. As the growing practice project，with the continuous and deep development of these activities，currently the college students' social practice activities of “Sanxiaxiang” are also facing a series of problems to be resolved urgently，including social identity，professional connections，funds guarantee and scientific assessment，etc. In order to promote the long-effect development of college students' social practice of “Sanxiaxiang” systematically，we need to further promote the social support and publicity strength，broaden and innovate the content and form of social practice，strengthen the mechanism for practice funds guarantee and optimize the mechanism for assessment.
