India is a multi ethnic, multi cultural country - i dont understand what you mean by AP's culture vis-a-vis "OURS" - call it "YOURS" please. Your culture could as well be very different from that of your neighbouring state & absolute alien 2 states hence. Since when has CHINA become the Guardian of the MONGOLOID RACE. That way let Kashmir go to Afghanistan (historical legacy), Punjab & Kutch (in Gujarat) to Pakistan, Tamil Nadu to Srilanka (they look lot alike), West Bengal to Bangladesh & that is it - END OF INDIA. Please have respect for the other's sentiment before you speak on racialially sensitive issues. For your information, HINDI is the spoken language at TAWANG & not any "TRIBAL/MONGOLOID/CHINESE" language. LONG LIVE ARUNACHAL PRADESH, LONG LIVE INDIA - JAI HIND.
