The dormitory of a bachelor is known as a "Poh", while a bachelorettes' one is known as a "Yanpo". However, women are not permitted to enter in the boys’ dormitory, although the reverse is permitted. Dormitories are built upon wooden raised piles, usually measuring four feet above the ground. The bachelors' dormitories are decorated with human skulls taken in head hunting, which are used for containing large log drums carved out from wooden logs. The drum, known as 'thum' or 'log-drum'. However, with the advancement of Western education, it has been witnessed that these practices are in decline. Headhunting, which once proved to be popular among the Nocte, has been banned in 1940 although the last head-hunting was noted in 1991 amongst the Wancho.
