All of the insects, animals and vegetation …
Years: 757 - 757
August
All of the insects, animals and vegetation in the besieged area of Suiyang have been eaten by August.
Zhang Xun orders thirty of his best soldiers, including his best soldier captain Nan Jiyun, to break though and seek help from nearby fortresses.
Nan Jiyun and twenty-six others successfully beak through; however, none of the nearby local governors are willing to offer troops and food supplies.
Finally, Nan Zhu Yun asks for help from Helan Jinming, governor of the nearby Linhuai.
Helan has long been jealous of Zhang Xun's abilities.
He also wants to preserve his forces, so he refuses to assist Zhang Xun.
He instead, hoffers Nan Jiyun a large feast in an attempt to persuade him to join his ranks.
Nan replies, "The reason why I risked my life to come here is because the local civilians and my comrades have no food to eat for over a month. How can I eat such a huge feast when I know that my comrades are facing? Although I failed my mission, I will leave a finger with you, as evidence that I did come here."
Immediately after, Nan Jiyun cuts off (or, in some versions, bit off) one of his own fingers.
He then rides away.
Nan Jiyun’s bravery finally convinces a local governor Lian Huan to lend him three thousand soldiers.
Both of them fight their way though the Yan ranks back into Suiyang.
Fighting though the numerous Yan army is damaging, and only about a thousand of the soldiers from the outside make it inside the fortress.
The starving Tang soldiers, numbering about sixteen hundred in total and with no chance of outside help, fall into despair.
Almost everyone tries to persuade Zhang Xun to surrender, or find some way of escape south.
