Dong Ying-zhen, an assistant surveillance commissioner of the coastal patrol circuit in Fu-jian, advised: "Under the old system, if coastal residents had private contacts with foreign yi, traded in fan goods, divulged information or led pirates to plunder the border areas, the major culprits were subject to the ultimate punishment, their families were banished to border areas, and those who were aware of the situation, but connived at it, were charged with the same crime.
