China is the biggest family with 56 ethnic groups. Among them, the Han Chinese is the largest and the most highly developed group. The Han Chinese can be found in many parts of China. They mainly live in the north plain region, the middle and the lower reaches of Yangze River and Pearl River Deltas. The other 55 groups are the minority ethnic groups. They are distributed in the mountainous areas of southwest and northwest of China.
Being too far away from big cities, the minority ethnic groups are poor in economy and there people are not well-educated. They have very few understandings of science and technology. So they must develop their economy.
To help the people of the minority ethnic groups live better, the government should take some effective measures. For one thing, more and more knowledgeable undergraduates should be encouraged to those poor areas to help the people there to get rid of their poverty. For another, the advanced science and technology must be introduced into the minority ethnic groups to improve their living conditions. More importantly, people of the minority ethnic groups should be given equal opportunities to study and work. Only so will China be more prosperous in the future.
