Referring to the land of the masterpieces of Co Phap - Dinh Bang, Bac Ninh, today, we are referring to one of the three famous historical "three ancients", the first Co Bi, the second Co Loa, the third Co Phap. Co Phap land is the most beautiful place in Kinh Bac, with sacred air. This is an area with many lakes and swamps, the Tieu Tuong River meanders and bends, the earth is shaped like a spider, spreading out like lotus petals. It is a precious earth grave, a legacy of emperors - corresponding to the 8 kings of the Ly dynasty, flourishing for up to 216 years. Currently, in Dinh Bang village, Bac Ninh, there are still imprints of the heroic spirits of the emperors. That place is the Do Temple, also known as Co Phap Dien or Ly Bat De Temple, where 8 kings of the Ly Dynasty were worshiped.
