Human beings are always in a process of dynamic development , and the social process in dynamic development is a process of so-cial change .The process of social change is actu-ally a process of cultural adaptation . In this process, various cultural phenomena change , sep-arate, aggregate, and regenerate; social relations are reorganized , social groups evolve , social life turns directions , and the structure and function of social institutions are changed , etc.This process of change is the process of acculturation . The process of the formation and development of the Bulang is a process of adaptation and search for survival opportunities in the process of natural and social changes .In order to survive , they have formed their own means of livelihood which can a-dapt to the natural environment;in order to devel-op, they assimilated compatible the cultural traits from the Dai, Han and Yi.They have shifted from a hunting and gathering society to a farming socie-ty, from a mountainous region to urban areas .In this process , they constantly adjust their own cul-ture so that it could develop in the course of con-stant adaptation . The acculturation of the Bulang is being nego-tiated in the process of adjustment to nature , as well as to the process of mutual interaction , learn-ing, influence and adoption with other surrounding ethnic groups .Following social change and adjust-ment, the local culture of Bulang will lose some of its original features , and get some new traits . And, it is just in the cycle of “change -adjust-ment-change” that the Bulang community gradu-ally changes its local culture and moves forward . Following the high-speed development of the human society , the speed of cultural change has also become faster and faster .Under such a back-ground, the developing countries , especially those minority nationalities in the developing countries , are facing a much more serious challenge .Accul-turation is the only way that can handle the chal-lenge, although this way is becoming more and more difficult.Speaking theoretically, accultura-tion is a two -way process .In other words , the cultural patterns of both groups who are in commu-nication with each other will change . The people who live in the process of this kind of cultural transformation will doubtlessly ex-perience dramatic cultural conflicts and imbalance , and might inevitably fall into confusion and wander astray, or even lose themselves .When Bulang are facing new cultural circumstances , they will be in-evitably alienated from society if they completely resist the mainstream culture , which will be against the development of their culture;If they negatively accept all the mainstream culture .It is possible that they will lose totally their original culture , and lose their foundation .When they are facing the im-pact of the mainstream culture , if they cannot ad-just the negative influences from “culture shock”, they will not only lose confidence in their own eth-nic culture , but will also have no identity within the external culture , live in a status of identity nothingness , wander between the two cultures , that is, stay in a “marginalized” situation.They will gradually lose themselves , and their long -term development will be influenced .That will be the worst result of acculturation .Therefore, the in-novation of new culture to adapt to the mainstream culture becomes the Bulang ’ s best way in keep-ing their original culture , and integrating into ma-instream society as well . Acculturation is a process in which one kind of culture learns from another kind of culture;it is also a process of producing new culture and con-structing culture patterns .Culture bearers , during the process of integration , constantly adjust their own cultural factors , and adapt to the mainstream culture while preserving their own essence so as to pursue for a long -term development . Only through preserving one ’ s own cultural essence can a nationality set up its ethnic confidence , and only when one has confidence , can one be self -reliant , and accordingly , pursue development . Only when one adapts to the mainstream culture , can one be accepted by the mainstream culture , and will he then , not drift away from the main-stream society, and can he, then, keep pace with the development of the mainstream society .There-fore, when we face the inheritance and develop-ment of Bulang’ s indigenous culture , we must be aware that the essence of the local culture ’ s sur-vival and continuation is that it constantly adjusts to its environment , and develops itself during the process of cultural change .That is to say it seeks development opportunities within acculturation , and that this should be the best way for the Bulang to move towards a better future .
