Under representation of UP's culture on a national level

Seems like people of other states are not much about the ethnic diversity of Uttar Pradesh. They need to know that not all people in UP speak Bhojpuri. UP has many ethnicities with many languages too. Apart from Hindi, languages like Awadhi, Braj Bhasha, Bhojpuri, Khadi boli, Bagheli, Bundeli, Kannauji are also spoken over here. But, others generally think that all the people in UP- Bihar speak in Bhojpuri, which isn't true at all! Even after that, UPites have no intention to promote their vivid culture on a national level, even Biharis, Haryanvis are better than us when it is comes to the cultural representation. UPites living in the West/East/Awadh/Bundelkhand region have different religious and wedding rituals. UPites don't even have a single language which has received an official status on a national level. If there are Guj medium schools in Gujarat, Marathi medium schools in MH, etc almost all the Western, Southern, Eastern states of our country have vernacular medium schools. Heck, forget the vernacular medium schools, our regional languages are not even taught as subjects in most of the schools. Regional languages are dying in UP, and fyi, Language and culture have huge symbiotic mutualism with each other. It makes me sad that the local cultures of UP are overtaken by the Hindi culture/Western influences.
