According to legend, when Agu fought Liao, he went on an expedition to Mobei and ordered his princess royal to escort rations and vegetables. Unexpectedly, I met the Liao army on the way, and the two sides fought fiercely. Because the Jurchen army was outnumbered, they all died. Big princess conveniently stuffed a few Chinese cabbages into the earthen pot before he died. When Akuta sent Jurchen troops to meet Fei Da, a clay pot filled with cabbage was found in front of Fei Da's body. Cabbage has turned yellow and softened due to the soaking of rain, and it gives off a strange sour taste. Akuta sadly buried Effie next to the pine forest on the hillside. Chop up some cabbages that big princess laid down his life to protect, stew pork, and the Jurchen army ate very well, and suddenly felt more physically strong. They shouted the slogan of revenge for big princess and the fallen soldiers, captured Pennsylvania City in one fell swoop, and won a great victory in the battle of Laishui (now Zhuolinhe). Later, Jin Shizong carved the famous "Daikin Victory Tuo Song Monument" as a memorial. And remember that big princess is a vegetable-stained bitch Busu.
