From their original homeland, Siyin valley, the Vaiphei wandered across the Tedim - Tonzang area and finally settled in Saikal area of present-day Mizoram and Churachandpur district and other districts of Manipur. At present the Vaiphei are over thirty thousand in population, outnumbering their brothers who remained in Sizang Valley. The Vaiphei and the Sizang are actually one people separated by international boundaries. They are descended from Pu Zahong (Nuai Mangpa), regarded by many historians as the Chief of the legendary Chiimnuai, the Garden of Eden of the Zo people.
