Personally, I fully agree with your idea because we don't want to see any unelected member of parliament in the house of parliament because they don't know what they should do.
Members of parliament should be elected according to the 2008 constitution. It's very difficult to amend this. We wish to amend it, but it's totally up to the wishes of the Myanmar military chief, because all MPs in parliament are talking, proposing, and asking questions under the direct instruction of the Myanmar military chief.
If these military MPs are not willing, it's not possible to amend the constitution, because it requires more than 75%.
