The full name of the gold medal is: "Gold signboard will be delivered immediately", which was established by the court during Xining period in the Northern Song Dynasty. It is the fastest, traveling more than 500 miles every day, and is mainly used to convey urgent military orders. It was directly issued by the emperor. The golden plate was not made by Kim Joo-sung, but a "wooden raft fan" with the emperor's orders written in gold. The recall of Yue Fei's twelve gold medals is this kind of "golden card rush". Zhao Gou won 12 gold medals in one day, which forced Yue Fei to retreat one after another and destroyed the excellent situation of resisting gold.
