How do historians regard the sage kings and the three cultural heroes today?

The correct answer is:

The three cultural heroes and the sage kings are considered mythical figures.

The three cultural heroes and the sage kings were two groups of mythological rulers or divinities in ancient northern China who in modern history have been designated dates in a period from circa 2852 BC to 2070 BC. Modern historians considered them culture heroes. Although the dates of these mythological characters may be fictitious, there are accounts of them preceding the Xia Dynasty.
