"Every summer vacation, the number of students heading overseas for travel increases 10 to 20 percent," said Xu Xiaolei, Chief Brand Officer of Aoyou.com, an online-booking website under China Youth Travel Service Co.

According to Xu, a study conducted by the website shows that most students prefer Singapore, South Korea, Japan, and other southeast Asian countries. The travel cost usually ranges from thousand yuan to 10,000 yuan, but some goes up to more than 100,000 yuan.

An employee at Chinese travel agency Caissa said they see a peak in number of students traveling overseas after national college entrance exam every year. Except short line tours for South Korea, Japan and Thailand, the long line tours for Europe and North America are also popular.
