Shi Lang was declared the "General Who Maintains Peace on the Seas" () and given the hereditary rank of marquis. At his own request, he was specially granted the privilege of wearing an honorary peacock feather. Shi Lang continued at his post in Fujian, seizing almost half of the developed land in southern Taiwan for his own profit. Shi annually extorted monetary resources from rich and poor local communities alike, and instituted policies that deliberately aimed to isolate Taiwan from the rest of the Qing Empire – coastal provinces were forbidden to interact with Taiwan, and even people from inland provinces were disallowed to bring their families with them, effectively preventing them from making any permanent foothold in Taiwan. Although he was later charged with arrogance, in 1688 the Kangxi Emperor received Shi Lang in audience in Beijing and allowed him to sit in the imperial presence, reiterating his confidence in him. Shi Lang returned to Fujian and remained in office there until his death in 1696.
