Ali-Ai-Ligang, the spring festival of the Mishing Tribe is the most colourful festival held every year on the first Wednesday (Ligange lange) of the month of 'Ginmur Polo' (February-March). 'Ali' means root, seed; 'Ai' means fruit and 'Ligang' means sow. That is why 'ceremonial' sowing of paddy starts on this day. A dance is performed by the young boys and girls, characterized by brisk stepping, flinging and flapping of hands and swaying of hips reflecting youthful passion, reproductive urge and joie-de-vivre.

"Poro Aapong" or rice beer, Pork and dried fish is essential for the feast. The festival continues for five days and during this festival certain taboos with respect to the cutting of trees, fishing, ploughing, burning jungles etc. are strictly observed.
