From the pie chart given above, we can observe that the professions structure of Chinese people experienced some changes during the past several years. From 1980 to 1999, the percentage of agricultural professions decreased by 30% from 68% to 38%. During the same period, however, service sectors increased rapidly from 5% to 22%. When it comes to the manufacturing professions, its percentage rose markedly from 27% in 1980 to 40% in 1999.
The pie chart reveals the phenomenon that there exists some difference in the development tendency among different professions in China. What exactly contribute to this phenomenon ? reasons can be listed as follows: for one thing, with the rapid process of urbanization, people in mounting numbers, especially youngster, have left their village homes ,moved into big cities and thus been out of agricultural industries. Moreover, quite a few people, especially college graduates hold that it is comparatively easy for them to make more money in the service industry. When it comes to the manufacturing industry, its transformation might be attributed to the adjustment of industrial structure: the authorities have issued some preferential policies to promote the rapid extension of manufacturing industry, thus, more workforces are required.
By observing the change over the past several years, we may forecast that the proportion of professions of service and manufacture will continue to rise. However, a high value should be placed on the development of agricultural industry by the public and the authorities. Otherwise, with the number of people who are engaged in agriculture diminishing, we will one day have nothing to eat! (262words)
