Many years ago, when China was poor and lagged much behind the world, a lot

of men went to California to seek for gold in the hope that they could be rich

There is a saying that man proposes, god disposes, which means man plan the

things and the rest of the outcome lies in the luck. This saying reflects the

connection between hard-work and luck, which is though sometimes we have worked

so hard, luck occupies great position, the unexpected things happen and refrain

us from succeeding. In order to be successful, people work so hard, they believe

they can achieve their goals, but lacking luck stops them achieving their goals.

So working hard doesn’t mean bringing people success directly, they just need to

try more times, without luck, they still can make their goals. Luck can help

people close to success, without hard-work, they can’t be successful. Hard-work

and luck make people realize their goals, but without luck, people still can

make it by trying more times.

When it comes to November 11, what’s on your mind? Well, as to the old

generations, it’s only an ordinary day; however, the young generations will

consider it as the Singles’ Day as well as the on-line shopping carnival. In

fact, on November 11th, 2013, Tmall and Taobao (the biggest Chinese online

shopping platform) has sold out more than 35 billion Yuan goods, this data has

astonished the media at home and abroad. Apparently, people have more interests

on cyber shopping than spend the night with their single friends. Some home

media even suggest that November 11th should be the Chinese on-line shopping

carnival.

Eleven”, aimed to encourage the single people to do something to celebrate their

own festival. Instead of dating lovers, people go on-line shopping to relive the

loneliness. According to the survey, China had 564 million Internet users at the

end of last year and 180 million single people. And the single people are the

main force of the China’s spending power. The debut was a great success. Then

“11.11” has an unusual meaning, which stands for on-line shopping carnival.

Comparing with the traditional shopping, the cyber shopping has more

distinguish features, which quite fit the young generations’ taste. People do

not need to go outside, just click their mouse, the goods will be home. The best

part is you can do it anywhere, anytime. All you need is a credit card. What we

can predict in the future is that on-line shopping is not going to fade away,

instead, it will boost like the mushrooms after spring rains.

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.
