What is "zawlbuk"

Zawlbûk ( or ) ( Mizo zâwl literally means ʻflatʼ, and bûk means ʻhutʼ) was a traditional bachelorsʼ quarters of the Mizo people, predominantly of the Luseis living in Mizoram, India. It was prominently the largest house in the tribal village, and it was customary for every village to have it constructed in the middle of the habitation. Even though its basic use was as a dormitory for all unmarried men of the village, it was much more a social institution where education, entertainment, skill and personal developments, and security of the tribal community were (almost) entirely centred.
