A group of dedicated teachers at a senior high school in Southwest China's Chongqing have recently won online praise for using their spare time to set up stalls in the school corridors to tutor students. They aim to help the students improve their performance in the upcoming National College Entrance Examination.

Statistics show that 13.53 million students nationwide will take this year's National College Entrance Examination, or gaokao, setting a new record high.

"The tutoring has been ongoing for three years," said Yuan Tianyong, principal of Chongqing Fengdu Tongwen School in the city's Fengdu county. This year, 57 teachers from the school's senior grade are helping about 900 senior students who are about to take this year's gaokao.

He said whenever the teachers are free, or when they grade assignments or prepare lessons, they prefer to move their desks from their offices to the corridor to make themselves available to answer the students' questions about their study and to provide guidance.

Yuan added that the teachers' companionship helps the students relax as the big exam approaches.

Through the unremitting efforts of the students and teachers, the number of students achieving the minimum required scores for the college entrance examination is steadily increasing, according to Yuan.
