I think I have only an incomplete address for an old friend. Can the post office in Viet Nam help to locate someone? It seems that all I have now is province, district and village level. It is a fairly small rural village Mê Pu in the Duc Linh disrict of Binh Thuan. I do not think the family has a landline phone. It may be impossible, but I do not know what resources are available. Any advice would be appreciated!
