Saturnina, tell me what Biharis are not good at. You can't imagine an India without Bihar. The Ashoka Chakra comes from a Bihari ruler, the chakra's central presence on Indian tricolor conveys how Bihar is prominent. India is known for Kamasutra which also comes from Bihar. The first democracy of the world was in Bihar (around 6th Century BC in Vaishali). Not enough space here to list everything Biharis have done for India.
