I want to know the answer to the following question:
Who were the three Liandong Han bannermen who were instrumental in the taking of southern China?
All the background I'm provided with is that "The three Liaodong Han Bannermen officers who played a massive role in the conquest of southern China from the Ming were Shang Kexi, Geng Zhongming, and Kong Youde and they". Is that enough to answer the question?
Answer: yes
