In late 228, Zhuge Liang launched a second campaign against Wei and besieged the Wei fortress at Chencang (陳倉; present-day Chencang District, Baoji, Shaanxi), which was defended by Hao Zhao. Cao Rui summoned Zhang He back to the capital Luoyang to discuss plans to counter the Shu invasion but they met in Henan instead. Cao Rui placed Zhang He in command of 30,000 troops and reassigned some of the Imperial Guards to serve as Zhang's bodyguards. He asked Zhang He: "General, if you're late, will Zhuge Liang have already captured Chencang?"
