Jiang Gan steals books-using double agents, heroes will be recruited by Jiang Gan-killing people with knives, Huang Gai pretends to surrender-risks, straw boats borrow arrows-bravado, argue with Confucianism-goad, skillfully borrow the east wind-golden cicada will shell out, and Pang Tong will sacrifice a series of tricks. Strategy is everywhere, and Kong Ming's war of words against Confucianism and Zhou Yu's intellectual stimulation are all symbols of strategy. Flexible use is best.
