[7] The city of Simhapura, now known as Trà Kiệu, had its perimeter walls built in the early centuries of the Common Era which support the above statements.
[3] Further mentions of Simhapura dating from the 11th century (1074–1076) when king Harivarman IV decided to restore the city back to its golden age.
[9] This deviates even from the later developed "Champa theory" explained above because Aurousseau believed Trà Kiệu to be the city that was invaded by China in the 5th century.
[9] This theory was based on the ancient Chinese records of the invasion and was a shot in the dark as the precise location of Lin Yi has remained uncertain.
[9] Another scholar, Andrew David Hardy, theorizes the name Lin Yi may have been used by the Chinese as a catch-all for a hostile Vietnamese polity.
[3] As with Aurousseau's theory, Hardy bases this hypothesis on speculation and on documentation of China's interactions with the Champa, as well as an elusive Vietnamese polity.
[1] The largest difference between Trà Kiệu I and II Phase lie in the styles of roof tiles found at the site.
The main difference in the styles of these tiles is that those excavated from Lũng Khê also feature lotus motifs, which are not seen in Trà Kiệu.
[1] In 1885, Catholic residents defeated a siege of the village by the Cần Vương movement, crediting a Marian apparition for their survival.
