There was an intense culture of violence already present on the island of Taiwan and this presented many problems for the administration and fortification of the island for the Sinican occupiers. Despite the heavy losses that had been done to the people of Taiwan many immigrants had come in response to a call for repopulating from the military, surrounding islands, and regular Sinican people to supply populace for Taiwan. Many of these became sympathizers for the Taiwanese dissidents who had recorded stories of the horror of the battle for their island. Others became loyal to the Emperor Zhangshao and against the native Taiwanese, many policies of discrimination were enacted.
