The southernmost district of Mizoram, and the parent district it came from
Background
Lawngtlai lies in the southernmost part of Mizoram, where the State's road network thins out among the hills. It was declared a district on 18th September 1998. Before that it came under Chhimtuipui district. Its own administration notes that the western belt of the district holds one of the highest concentrations of minority population in India. Lunglei and Siaha districts cut Lawngtlai into two parts, and much of it is hard to reach, which is why road building counts for so much there. Lunglei district lies to its north-east, as Lunglei's own administration records. A district drawn this recently shows how much Mizoram's internal map has changed since statehood. The two points worth holding are these: the district in the southernmost part of the State, and once part of Chhimtuipui.
In plain words
Chhimtuipui A former district of Mizoram — An older district of the State whose area was later divided.
