    As is depicted in the graph, the number of international students in China in the past four years rose from 260 thousand in 2010 to more than 350 thousand in 2013 with an annual increasing by about ten percent.

    Actually, it is not difficult to find the reasons. First of all, China's comprehensive national power is much stronger than before and China became the world's second largest economy in 2011. With great impact in the world, China is attracting more and more overseas students. What's more, China has a civilization of 5, 000 years, which greatly appeals to those who want to learn Chinese unique cultures. Last but not least, with in-depth international exchange, China is willing to open the door to overseas students to make them know China better.

    In conclusion, with the development of China, an increasing number come to study in China and they will be welcome to China.
