Just two weeks into the summer vacation, a total of 57 teenage students have been reported missing, more than twice the number last year. While, based on past records, most of them would eventually be found or go back home themselves, it's always a grueling experience for the parents.

Under the hot summer sun, the grandpa searched for his 7th grade grandson who has been missing for 3 days;

the student would always forget to return home during summer as he is from a family where both parents work and the grandfather could not have control over him.

The grandpa went to many places his grand child might show up, including Internet café and asking all customers.

He also went to comic book rental shops to try to find him.

The grandpa is not the only one to search for missing young people during summer; according to Children welfare league foundation,

there has been 57 calls on missing children on the first 14 days of summer vacation, which is twice the number of the same period last year.

Most children would spend too much time in Internet Cafes or at friends place and would usually return home after a week.

Parents should be aware not to leave their children at home alone, if they got out and get lost, it would be hard to find them.
