Impossible to determine - the Ming did, true enough. However, we just don't know beyond that. The Yuan had the Mongol banner as theirs, and beyond that dynasty, there's no records, as far as I know, of what they primarily had on them.

That being said, they did all have their own unique characters. However, the Ming doing that, as far as I know, was more a reaction to the Mongols than anything - i.e. demonstrating their "Chineseness."

Past that, each dynasty did have its own symbols, kinda like the USA and the eagle. For instance, with the Han, fire and the lotus were some. Couldn't possibly say if either was on their banners, however.

Basically, just about whatever you decide for the banner/flag would work, so long as it is "Chinese."
