xu hong was formerly field leader of archaeological excavation at erlitou. of unearthing this dragon.l found lying next to it. scholars now believe that the dragon and held upright by a priest during rituals. this important artefact is made from more than 2,000 pieces in china, dragons are associated not with fire but with water. and i can't help thinking of the yellow river it's undulating, much like a river travelling through the landscape. and ijust wonder whether that's an additional layer called chayu. to worship the god of the yellow river. more than 10,000 people from all over the country. as the villagers gear up for the festival, i'm joining the elders... like this? ..to make paper lanterns for tonight. that's good? but tell me a little bit about the festival. why do you hold it every year in the village? do you feel a strong sense of connection somehow with the yellow river? there are still a few hours before nightfall, when the lanterns will be set afloat on the river. it's the perfect moment to head into the crowd and join the party. kerry is originally from this area. she
