With the rapid development of information technology, it is inevitable for the distributed mobile computing will evolve to the pervasive computing gradually and whose final goal is fusing the information space composed of computers with the physical space in which the people are working and living in. Furthermore, with the development of SOA, more and more pervasive applications have been composed of different kinds of services. So how to choose a suitable service from all the useable services is the most important step for pervasive computing. Compare to the traditional service selection we must take more care of the context as well as the quality of them in pervasive environment. However, most of existing researches pay no attention to QoC(Quality of Service) which may lead to unreliable selections. Therefore we proposed a middleware based service selection scheme to support QoC-aware service selection efficiently.

Dragon dance in the ceremony of Huayao Yi people's Festival of "Offering a Sacrifice to Dragon" is a sacrificial culture developed on the basis of Chinese ethnic culture and oriented to ethnic traditional sports. This Festival is one of the representative ethnic celebrations of Huayao Yi people. Its rituals of offering a sacrifice to dragon and dragon dance are not only the everlasting epitomes of the ethnic culture, but also the typical models of ethnic traditional sports. Meanwhile, "Huayao Yi" is Nisu branch of Yi people and descendant of ancient Qiang people. Females participating in dragon dance would wear a mysterious veil. Hence, making a deep excavation on its culture becomes a historical mission. In this context, it is necessary to make research on this ancient ethnic sport system.
