I don't find where is Panyang. There is a village called Tanyang in Zhangpu County, Zhangzhou City. Do you mean this? It seems there is no direct flight from Doha to any cities of Fujina. Suggest you take a flight to Osaka or Shanghai and then transfer to Xiamen, which is closed to Zhangzhou City. You can get there by bus. If it is the place, I would like to help more if you need.
