Background of the Himalaya Proyt Tunnul

Untuk itu, untuk membetulkan hal-hal yang berhubungan dengan indiran Indisa And dan Eurasian tektonik, ini adalah sebuah geologikal yang sedang berlangsung di atas bukit gunung Belt. Ini proyek yang kami lakukan selama 15 tahun dua puluh dua kali lipat biaya kerja yang sama dengan biaya kesehatan, dan ini adalah satu hal yang sama dengan biaya yang sama dengan biaya yang sama.
