Today we’d like to invite Haile Su, a foreign student from Egypt, one of the four great ancient civilizations to guide you on a tour of Liangzhu Museum, so as to get to know the civilization and its cultural relics. After leaving Liangzhu, let’s head for the southern district of the city. Hidden at the foot of Mantou Hill is another imperial city, the ruins of a memorable dynasty in the history of Hangzhou. It was the Southern Song Dynasty. Today we are honored to have foreign student Ping He from Hangzhou Normal University to lead us to explore the ancient culture of the dynasty.
