Is “Whether he is the same person as Emperor Ku” true?

In the "Classic of Mountains and Seas", the supreme god "Emperor Jun" appears frequently. However, in orthodox historical texts such as the "Records of the Grand Historian: Annals of the Five Emperors", the name Emperor Jun completely disappears, replaced by "Emperor Ku". Due to many overlapping deeds, later generations often merged them, but in early classics, Emperor Jun of the "Classic of Mountains and Seas" and Emperor Ku of the "Records of the Grand Historian" were independent of each other. The original text of the "Classic of Mountains and Seas: Classic of the Great Wilderness: East" reads: 「羲和者，帝俊之妻，是生十日。」 The original text of the "Records of the Grand Historian: Annals of the Five Emperors" reads: 「帝喾高辛者，黄帝之曾孙也。」
