I want to know the answer to the following question:
Which two ethnicities made up the majority of the Banner Armies?
All the background I'm provided with is that "It was in Qianlong's reign that the Qianlong Emperor, concerned about maintaining Manchu identity, re-emphasized Manchu ethnicity, ancestry, language, and culture in the Eight Banners and started a mass discharge of Han Bannermen from the Eight Banners, either asking them to voluntarily resign from the Banner rolls or striking their names off.". Is that enough to answer the question?
Answer: no
