Fu County
When he was at Yinping, Deng Ai came up with the idea of taking a shortcut through Deyang Village to Fu County that would lead them to an area about 100 "li" west of Jiange and about 300 "li" from the Shu capital Chengdu. His idea was to lure Jiang Wei to send reinforcements from Jiange to Fu County and weaken Jiange's defences; if Jiang Wei did not send reinforcements, Fu County would be isolated and easily conquered.
