I am planning a trip to Xiamen and Zhangzhou to look for my ancestor village. Our family name is Chen and the ancestor village is written in our family record as "upper hamlet of Yu-chow, Szu-pi Erh-shih-pa-tu, Lung-hsi-hsien, Chang-chow-fu". Please help locate the village for us and write its name in pinyin. Thank you very much for your help.
