(1),《旧唐书》卷41?岭南道?崖州:“隋珠崖郡。武德四年平萧铣置崖州,领舍城、平昌、澄迈、颜罗、临机五县。贞观元年置都督府,督崖、儋、振三州。其年,改彦罗为彦城,平昌为文昌。”文昌县:“武德五年置平昌县,贞观元年改为文昌。”(北京,中华书局,1975年,5册,1761页)。
《读史方舆纪要》卷105?广东?琼州府?文昌县;“平昌废县,在县西北。志云,本武德县,隋置,属崖州。唐改为平昌县,后改曰文昌移于今治。”(北京,中华书局,1955年,5册,4326页)。
据此,作武德五年改武德县为平昌县。

《嘉庆一统志》卷450?琼州府?古迹:“文昌故城,在今文昌县北。通志,故县在今县北何恭都潭步村,元至顺二年移于北山都,即今治。”(《四部丛刊续编》,商务印书馆,1934年,170册)。
宣统元年《广东地舆全图》文昌县图:文昌县北有何恭都有“旧平昌县治”。(台湾,成文出版社《中国方志丛书》第108号)。今文昌县北有平昌村,当是。
