...In part of East Asia,
Back in time of Hong Bang
Lately in the ages of Tran and Ly dynasties,
Our people were pure and brave.
We beat the army of To Dinh
At Linh Bieu
And defeated Ma Nhi
in the battle of Phu Luong
We also overthrew the Chiem Thanh (17)
In fighting
And destroyed the Chan Lap (18)
With weapons. ... This poem shows us on the one hand they described the old properous Vietnam as a country which has successfully resisted all the aggressors, like To Dinh or Ma Nhi, from China, and on the other hand as a strong conqueror of the south minorities like Chiem Thanh and Chan Lap. According to them, the fact that the Vietnamese destroyed and absorbed the other weaker races was not a blot but a brilliant achievement upon their history.

(17) Chiem Thanh was Cham or Champa who built the Kingdom in central Vietnam.
(18) Was an old Kingdom of Khmers
