The persons, who belonged to Tlangsam village, were received at Zokhawthar, a border trade centre, by the Deputy Commissioner of Champhai district H Lalengmawia.
They were freed after Mizo civil societies took up their case with the Myanmarese authorities.
Twenty people from the village, calling themselves 'spiritualists', had planned to travel to China via Myanmar last March. While one of them died in the prison, 19 others were freed.
