The Chang Naga tribesmen of Nagaland, India, traditionally used the rice beer mug as their cup for drinking purposes. The bamboo mug is 26.2 cm tall and elaborately decorated with finer poker-work designs. Carved sculptures are corresponding cultural and social important artifacts for tribes, which testify to the aesthetic culture and social manners of its tribe populace.

These fermented drinks were for rituals, celebrations, and daily tasks together with rice beer, popularly called "Zu" among the Naga tribes. It is distributed during festivals, ceremonies, or any other gathering for coordinating a community spirit. Bamboo-made mugs intended solely for the drinking of rice beer are decorated with traditional designs and motifs, symbolizing tribal symbols or nature.
The poker-work burning-with-hot-tools-on-the-surface-of-bamboo-for-decoration technique not only contributes to the aesthetics but also glorifies the exceptional skill of the Chang Naga creators. In this way, it works in favor of the protection of their craft with a personality and identity of its own. The rice beer mug in question comes under Anthropology and is in the collection of the National Museum in New Delhi. It acts as a cultural symbol representing the traditions of the Chang Naga tribe, their artistic skills, and the significance and function of rice beer in their social customs.
