I'm not sure specifically what the 'new bangla story' is about as you haven't provided more details. It could be about various aspects of Bengali culture, history, or contemporary life in Bengal.
Once upon a time in a small village in Bengal, there was a young girl named Rina. She was known for her kindness. One day, she found a little bird with a broken wing. She took it home and nursed it back to health. As the bird recovered, it brought a sense of joy to her family. The bird would sing beautiful songs every morning, and soon the whole village would gather around Rina's house to listen to the bird's sweet melody.
It could have traditional Bangla elements incorporated to give it a local flavor. Also, the characters' voices and dialogues might be adapted to suit the Bangla language and culture. The music and sound effects might be designed to enhance the overall experience.
Panu was a young lad in a Bangla village. He had a great love for adventure. One time, he heard about a hidden cave in the nearby forest. Without hesitation, he set off to find it. After hours of searching, he finally discovered the cave. Inside, he found ancient paintings on the walls. He was so fascinated by them that he decided to share this discovery with the whole village, and soon the village became a popular place for those interested in art and history.
