Some questions on 'rice' (eating, growing, ...) tradition (or technology?):
Where is evidence that people (now living in the Altai region) ever grew rice?
Did Thais carry the tradition over mountains to find water-logged plains to continue the rice tradition?
Where Thai (today) rice growing come from?
(One answer may be 'rice' was here long before Thais came. --Who are the indigenous agricultural peoples?--
Another may be Thais were also here with rice long ago. --What did 'Ban Chiang' people grow and eat?)
There are enough for history learners to ponder --to find better fit history; to learn from 'more true' history.
Is it time we reject 'lies' about history?
Is it time we reject 'lies' about present government?
