Students' information is easily collected and sold to scammers who prey on trusting people

Xu Yuyu, a college-bound student, died from a sudden heart attack on Sunday after tuition fees raised by her family were swindled in a telephone scam.

The 18-year-old from Linyi, Shandong province, scored 568 points on her college entrance exam this year and was admitted to Nanjing University of Posts and Telecommunications.
