In 2009, during the Pingyao Photography Exhibition, Xiao Zhao, a patriotic young man studying in high school, shouted for the Diaoyutai anti-Japanese. Xiao Zhao’s family is poor, and he has to ask relatives to borrow money for college entrance examinations. Finally, he was admitted to the National University, determined to study against American imperialism. Newton said that there are gravity and anti-gravity in the world, and there is still room for free thinking in college life, so Xiao Zhao went to Daliang Mountain to teach. Later, when Xiao Zhao's family changed, he went through demolition and his grandfather passed away. Xiao Zhao's original pure and beautiful feelings for the country gradually disappeared, and he began to learn to think.
