Sui Yangdi
The (c. 230) Guangya (; "Expanded "[Er]ya"") was an early 3rd-century CE Chinese dictionary, edited by Zhang Yi (張揖) during the Three Kingdoms period. It was later called the Boya (博雅; "Bóyǎ"; "Po-ya"; "Broadened [Er]ya") owing to naming taboo on Yang Guang (楊廣), which was the birth name of Emperor Yang of Sui.
