No, it isn't. 'Ye Un Dino Ki Baat Hai' is a work of fiction that may draw inspiration from various elements but is not based on a true account. The characters and events are crafted by the writers' imagination.
Without more context, it's hard to tell the full story of 'yeh un dinon ki baat hai'. It might be a story about old times, perhaps reminiscing about certain events, relationships or situations that happened during a particular period in the past. But this is just speculation.
I don't really know the significance as the information is so scarce. It could be significant to those who are directly related to the real story it's based on, like family members or friends of the people involved in the original events.
The theme might be change. Maybe it's about how things were in the past ('yeh un dinon ki baat hai') and how they have changed now. It could show the contrast between the old times and the present in terms of society, culture, or technology.
The phrase 'yeh un dinon ki baat hai' gives very little to go on. If it's a real story, it could cover a vast range of topics. It could be a story of a family during a war, how they survived, the sacrifices they made. Or perhaps it's about a group of friends and their adventures in a bygone era. But without further information, we can only guess what this real story might be about.
As I don't know the exact nature of 'yeh un dinon ki baat hai', it's difficult to give details. However, if it's a story about past days, it might include elements like the way of life at that time, the social norms, the way people interacted, and the events that were significant during those days. But again, this is all just general speculation without knowing the real story.
I'm not entirely sure which specific 'yeh un dinon ki baat hai based on real story' you are referring to. There could be many stories or works with such a title. It would be great if you could provide more context.
