Who do you refer to "our ancestors"???? Ancestor means ບັນພະບູລຸດ so this question is not quite right. However, I believe that we or our generation will still be able to enjoy the beautiful scenery of Laos with improved living standard including better housing.
First photo probably not, it will be underwater, second photo Kuan sii falls? yes no problem, 3d photo Vang Vien again no problem. 4th photo I don't know where it is.
Living standards and houses?? ha ha ha, fairy tales for children. More likely Lexus and European vacations for a very select corrupt few today, bankrupt tomorow, Money to China and Vietnam, poor people to Laos.
