Zhemgang is one of the remote districts in the country. The annual tshechu is the biggest festival in the district and was introduced after the inception of the Rabdey in 1966. Different mask dances are performed during the festival. The highlight of the festival is the unfurling of the huge Thongdrol (large tapestry) of Guru Rinpoche. It is believed that the mere sight of the Thongdrol cleanses one of all sins.
