Well, in the 'big mom is luffy's mom fanfic', they might have crafted a story where Big Mom is Luffy's mom. But it goes against what we know from the official 'One Piece' story. Fanfictions like this can be really interesting as they can rewrite the story in unexpected ways. They might have some interesting plot twists and explanations within the fanfic to justify this relationship, but it's not part of the main 'One Piece' universe.
Zhuge Liang was a famous politician, strategist and writer in Chinese history. He was described as a fairy-like figure in Romance of the Three Kingdoms. However, from the perspective of historical facts, there was some controversy about whether he was really as divine as the book said.
Zhuge Liang's military and political performance was widely regarded as one of the best generals in Chinese history. During the Shu Han period, he had led many important wars, such as the empty city stratagem, straw boats borrowing arrows, etc., demonstrating outstanding commanding skills and courage. In addition, he also put forward many important strategies and suggestions, such as "Longzhong Dui" and "Three Divides of the World", which had a profound impact on the development of Chinese history.
However, there were also people who questioned Zhuge Liang's immortal image. They believed that the Zhuge Liang depicted in the Romance of the Three Kingdoms was an exaggerated image that lacked some details and evidence from real history. In addition, Zhuge Liang's political and military talents were also controversial because he was sometimes too cautious and conservative in political decision-making and military strategy.
Zhuge Liang was a respected and controversial figure in Chinese history. His deeds and spirit had a profound impact on Chinese culture, but whether he was really as divine as the book said needed to be objectively analyzed from many angles.
