The origin of the Mangmetong village.
From the beginning, Longkhum was a big village whose population was too high. Since the population kept increasing, a group of people left the village and settled in another village. They named this village Reto village which was five kilometers away from Longkhum village.
As time passed, Reto village also increased in population because people from neighbouring villages migrated and settled there. As a result, the villagers faced water scarcity. Nungshikaba was the chief of that village who was a rich and selfish man by nature. There was only one pond in that village, and the chief being a selfish man by nature fenced it so that the villagers could not draw water from it.
Being rich seedlings were also at the disposal of the chief only. The villagers depended on the chief for seedlings but the selfish chief gave them boiled seeds, and as a result the villagers could not grow crops. It continued for many years and the economic condition of the villagers changed from bad to worse. With the passage of time, the villagers began to despise him for his selfish nature. They got tired of him and decided to desert him.
The chief had a daughter named Yasanaro who was engaged to a man named Arenchang. But before marriage, Yasanaro died. At the time of mourning the villagers decided to leave the village. People slowly began to abandon the village, one after the other. Aremchang gave the news to Nungshikba about the people deserting the village, and asked what they should also do. Nungshikba also decided to leave the village together with the people.
However, there was a problem because they still had not buried the body of Yasanaro. According to ancient Ao custom, the dead body in the case of a girl cannot be buried without completing the five days of mourning . And since the five days were still yet to be completed, they could not bury the body. As a result, Nungshikba asked Aremchang to carry the dead body of Yasanaro. Together with the dead body, the family also left the village.
In the course of their journey, they happened to cross Longkhum village. But the villagers of Longkhum did not allow them to cross the village with the dead body. Feeling pity, the Longkhum villagers paved a new path for them to cross. This path is called Lenpipok( made a path), and exists till today.
About three kilometers away from Longkhum, there was a village named Merasa yim. Nungshikba and his party took rest in this village. Having been in love and seeing the dead body of his beloved, Aremchang sang a melancholic song. On hearing the song, Nungshikba asked Aremchang to leave the dead body behind, they continued their journey.
Since then, Merensa village came to be known as Mangmetong village.
