Origin Story
战国时期，齐国和燕国之间发生了一场激烈的战争。燕国军队实力强大，包围了齐国的城池，齐国军队节节败退。齐国的大将田单想出了一个奇计，他利用了燕国将领的贪婪心理，派人送了一批金银珠宝给燕国的将领，并且偷偷地把燕国军队的粮草全部运走，然后带领齐国军队突袭燕国军营，最终取得了胜利。这场战争中，田单的出奇制胜之计，成为了后人学习的典范。
During the Warring States period, there was a fierce war between the states of Qi and Yan. The Yan army was powerful and besieged the cities of Qi, forcing the Qi army to retreat steadily. Tian Dan, a general of Qi, came up with a brilliant plan. He took advantage of the Yan general's greed and sent a batch of gold and jewels to the Yan general. At the same time, he secretly transported all the Yan army's food and supplies away. Then he led the Qi army to surprise attack the Yan army camp, and eventually won the victory. In this war, Tian Dan's surprise attack became a model for future generations to learn from.
