The Censor Huang Zheng-se, regional inspector of Guang-dong, memorialized four proposals for defending the pearl beds: "1. Increasing the number of government troops controlling the strategic positions. 2. Retricting weapons on ships so as to eliminate those things which assist the pirates. 3. Carrying out separate detailed investigations so that the entry routes can be blocked. 4. Severely punishing the accomplice-merchants (窩販) so as to stop their clandestine receiving of goods." All of the proposals were approved as submitted.
