銆€銆€The excavation to the fourth archaeological point of the Suitang Grand Canal (Sixian county-section) has just ended. During the excavation, archaeologists found not only many cultural relics, but also 20 footprints suspected of being left by people of the Song Dynasty. This is the first time that clear footprints have been found since the beginning of the excavation.
