The Depopulated Shore of Fujianese

Newly homeless coastal residents pressed gangd into labor, I think. They were hired to set fires and do other work. The flood of refugee coastal dwellers caused trouble for their fellow Fujianese on the other side of the boundary. There's an amazing quote from that book you mentioned earlier. Even today, although the coastal wall has long since disappeared, a folk tradition in Pujian remains. A good woman doesn't marry a man outside the boundary.
