 Stories including Zhou have also been used to educate . The Secondary School system of Hong Kong teaches children the value of <unk> by making them read about the close teacher @-@ pupil relationship between Zhou and Yue . A morale tale called " Yue Fei Studies <unk> " in Children 's <unk> , a Chinese magazine tailored for children ages two through seven , demonstrates how great achievements are only made possible via <unk> practice . The story states how young Yue stumbles upon Zhou 's training hall in a neighboring town while gathering fire wood . Yue applies to become a student , but Zhou tells him he must first practice the art of the " far @-@ sighted person " by staring into the morning sun to improve his eyesight . After years of <unk> practice , Yue is able to spot a lone <unk> flying off in the distance and two <unk> on a tree far into the forest . Zhou then officially takes him as his disciple and adopted son . Under his tutelage , Yue is able to master the eighteen weapons of war and to shoot a falling leaf from one @-@ hundred paces away .
