In 1670, when the Kangxi Emperor of China's Qing dynasty was sixteen years old, he issued the Sacred Edict, consisting of sixteen maxims, each seven characters long, to instruct the average citizen in the basic principles of Confucian orthodoxy. They were to be publicly posted in every town and village, then read aloud two times each month. Since they were written in terse formal classical Chinese, a local scholar was required to explicate them using the local dialect of the spoken language. This practice continued into the 20th century.

The Kangxi Emperor, also known by his temple name Emperor Shengzu of Qing, personal name Xuanye, was the third emperor of the Qing dynasty, and the second Qing emperor to rule over China proper. His reign of 61 years makes him the longest-reigning emperor in Chinese history and one of the longest-reigning rulers in history. He is considered one of China's greatest emperors.
