As I have no knowledge of this 'khan khan se guzar gaya' story, I can't describe its plot. It could be about two characters named Khan, and something that happened between them or to them which led to the events of the story. But this is just speculation without proper information.
I'm not entirely sure as 'yum stories' is a bit unclear. 'Kahan kahan se guzar gaya' could roughly mean 'has passed from here and there'. Maybe it's about some stories that have come from various places or experiences.
Since I don't know the exact 'khan khan se guzar gaya' story, it could be a story specific to a certain region, culture, or community. It might be about a person named Khan and his experiences that he has 'passed through' (guzar gaya), but without further details, it's hard to say more.
Well, 'kahan' means 'where' and 'guzar gaya' means 'passed by'. But 'khan khan say' is a bit unclear without more context. It could potentially be some sort of expression related to a person named Khan or something specific within Urdu grammar or cultural usage that I'm not entirely sure about without further research.
In caravan fantasy fiction, the caravan often serves as a mobile home. For example, in many stories, it's where the characters sleep, eat, and store their belongings as they journey through the fantastical world.
In a fanfic, a caravan in the distance could symbolize hope or danger. If the main character is lost or in trouble, seeing the caravan might mean rescue is near. However, it could also be a caravan of outlaws. The wagons could be old and rickety, with tattered awnings. As it gets closer, the sounds of the caravan become audible, like the jingling of harnesses and the low murmur of voices.
The Mexican caravan was a large group of migrants mainly from Central America traveling through Mexico towards the US. Many were fleeing violence, poverty, and lack of opportunities in their home countries. They hoped to seek asylum in the US. However, this caravan became a highly politicized issue in the US, with some seeing it as an 'invasion' which was an inaccurate and unfair view as these were mostly desperate families looking for a better life.
