It is completely unacceptable. In a civilized society, we should focus on positive, educational and family - friendly content. Stories with sexual content are not suitable for public consumption and can violate social norms.
I'm not sure specifically about this 'girl on the train hindi story' without more context. It could be about a girl's journey on a train, perhaps her experiences, the people she meets, or some sort of adventure that takes place during the train ride in a Hindi - speaking setting.
No, it's not a proper phrase in standard English. It seems to be a jumbled combination of words. In proper English, we would expect a more grammatically correct and clear construction.
To train in Hindi storytelling, first, listen to lots of Hindi stories. You can find them on platforms like YouTube or Storytel. Notice how the narrators use intonation and expressions. Then, start with simple stories and practice retelling them in your own words. Try to use the Hindi you've learned so far.
As I don't know the story, I can't say for sure. But probably the girl herself is a main character. There might also be other passengers, the train conductor or some people she meets at the stations.
Most likely, the main character is the girl. In stories that are named in such a way, the named entity is usually the one around whom the plot revolves. In this case, it's the girl on the train. She could be of any age, from a young girl to a young woman, and her actions, decisions, and experiences would be what drives the story forward in the context of the train journey.
It's not entirely clear without more context. 'Sex' refers to sexual activities in English. 'Hindi' is a language. So perhaps it could be a sex - related story in Hindi, but it's very ambiguous.
No, it's not appropriate. We should promote a positive and healthy cultural environment. Content like this is not only unethical but may also have a negative impact on the psychological health of those exposed to it.
