Empress Xiaochengren, of the Manchu Plain Yellow Banner Hešeri clan, was a posthumous name bestowed to the wife and first empress consort of Xuanye, the Kangxi Emperor. She was empress consort of Qing from 1665 until her death in 1674. Although her marriage was a purely political one, the Kangxi Emperor was very fond of her and left the position of empress vacant for about three years after her death.

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.
