At that time, the maritime ban in Guangdong was not strict. As long as fishermen went to a remote coastline, they could still go into the sea to fish. Therefore, there were many fishing villages within five miles of the coast. The pirates often went ashore to plunder, and this was when they realized that the Guangdong Navy was much inferior to the Fuzhou Navy. This emboldened them to rob all the way from the fishing villages to the towns. There was once when they almost entered the county.
