Because of "the miasma is too strong", soldiers often get sick. In order to improve the soldiers' life and keep fit, Zhuge Liang remembered the hometown food "Ju Guo Cage Bao", so he ordered the soldiers to slaughter pigs and kill cattle, chop beef and pork into paste, put the Millennium ginkgo fruit into it and wrap it into meat buns. According to the eight diagrams, put them in a cage and steam them, so that each soldier can eat one group for each meal. The soldiers were greatly refreshed after eating, and soon eliminated the patients, and everyone praised the "eight-happiness cage bag."
