 Zhou continued to teach the children until his death , prior to Yue 's legal adulthood . Following his passing , Yue became extremely depressed since Zhou had been the greatest influence on his early life . Zhou 's student would regularly visit his tomb on the first and fifteenth of every month with sacrifices of meat and wine and would shoot three arrows in succession with one of the two bows his tutor had presented him with ( it is never mentioned whether any of Zhou 's other archery pupils came to visit his tomb ) . Dr. Kaplan comments this continuous unusual display of mourning " went far beyond the ceremonial appropriate for even a highly respected teacher " . Noted <unk> <unk> Wilhelm claims even though the display of grief was genuine , it was also a way of <unk> the stories of his heroic idols and " [ establishing himself ] in the public eye " . Yue 's father later followed him secretly to Zhou 's tomb after striking him during an argument over his melancholic behavior . There , he saw him perform the unorthodox <unk> involving the meat , wine , and three arrows . When he finally confronted him , the son confessed that " his gratitude for Chou 's instruction could not be <unk> simply by the usual first and middle of the month ceremonies and so he ... shot off the three arrows to symbolize that Chou had been the source of his inspiration as an archer " . Dr. Kaplan 's states this happened just prior to Yue 's entrance into the army and that the entire event served as a symbol for Yue 's " entrance into responsible <unk> " .
