Primary students stand with bowls on their heads during a special mid-term examination at Nashan School in Huizhou, Guangdong province, Nov 20, 2013. A principal from the school said that the idea of balancing bowls on students' heads to test their posture came from a teacher who watched a dance program "The Pagoda of Bowls". The comprehensive quality evaluation of the students comprised eight parts, including their sitting posture and personal hygiene. Six students received point deductions for their standing postures because they failed to keep bowls on their heads for 10 seconds. [Photo/icpress.cn]
