    Many of us may have experienced the pleasant moment of seeing recommended  songs after we listen to some songs on a music app. When we open shopping websites, we often see things we want to buy on the home page. The businessman can decide which is the best place to build a new entrance in a big supermarket in the city center. If you want to take a taxi on a taxi app, it can even guess where you want to go before you tell it! Aren’t these things amazing?

This is based on data (数据). Data is no longer only about numbers, but information from almost every side of our lives: our shopping habits, interests or what we eat. All of this is called “big data”. In December, 2017, President Xi Jinping called for China to speed up its big data strategy (战略) to better serve social and economic (经济的) development. As a result, people’s lives can be improved as well. He also asked for greater use of big data in areas like education, social security and transportation.

We have seen big data being used more often in China in the past few years. The role it plays in tourism ( 旅 游 业 ) is just one example. Many travelers today like to share their experiences with others on the Internet. All the data that travelers share online is helping the tourism industry get a lot of information. After the data is analyzed (分析), these tour sights can know about travelers’ needs better. In this way, services will be improved, which is helpful to the development of the whole industry. As a result, travelers can expect better tours in the  future.

Moreover, big data is also an important growth tool for economic development. With  growth rate of 30 percent every year, sales of big data industry in China will reach one trillion yuan yearly by 2020. Having so many good influences, big data is sure to be seen more and more in China.
