A police dog nicknamed "Yangjiang" goes through an obstacle course under the guidance of handler Zhang Weidong, during a training exercise in Hangzhou city, Capital of East China's Zhejiang province, Sept 10, 2011. Sept 10 is the first day of the three-day Mid-Autumn holiday that is celebrated on the 15th day of the eighth month on the Chinese lunar calendar, and falls on Sept 12 this year. To ensure the safety of the upcoming China National Paralympic Games, which will be held in Hangzhou, police dog handlers of a detachment of Zhejiang Armed Police Corps spent their Mid-Autumn Festival, which is known as a time for being with family, on training exercises with their beloved dogs, though the intimate connection between handler and canine shows that they are like family members to each other.
