From the infornation given in the above clomun chart,we can see an increase above all in the number of students going to china from abroad from 2006 to 2016.There has been a gradual increase from 154 thousands to 262 thousands students going to China from other countries from 2006 to 2008.While it has a dramatic increase from 2008 to 2016.
At least two fundamental factors have contributed to this phenomenon.On the one hand, Chinese economic condition got better and better from 2006 to 2008,while which didn't benefit education entirely during this period.On the other hand,the Olympic Games was held in Beijing in2008,which strengthed the communications between Chinese and other countries,make foreign people know and like China,and go to study in China.
In conclusion,the number of students going to China from other countries has increased more than three times,which can indicate that our country's educational level got higher and higher.Meanwhile,it can countribute to enlarge the influence and improve the state of china.
