Zhu Biao (Chinese: t 朱標, s 朱标, p Zhū Biāo; 10 October 1355 – 17 May 1392) was the Hongwu Emperor's first son and crown prince of the Ming Empire. His early death created a crisis in the dynasty's first succession that was resolved by the successful usurpation of his brother Zhu Di as the Yongle Emperor, an act with far-reaching consequences for the future of China.
While his father completed his rebellion against the Yuan Dynasty, Zhu Biao was generally kept away from the front lines and provided with the most esteemed Confucian scholars of his time as tutors. Particularly by comparison with his father or brother, Zhu Biao is remembered as being soft-hearted. The official History of Ming records him once questioning his father why so many of the ministers and generals who had aided him in forming the Ming Empire were being rewarded with death or banishment. His father replied that they were like thorns on a vine; not trusting Zhu Biao to do it himself, the Hongwu Emperor was kindly removing them before passing it on to his son.
Like his son, the Jianwen Emperor, Zhu Biao had a deep appreciation for traditional Chinese culture: he was involved in a survey of Xi'an and Luoyang as potential capitals for the dynasty when he fell ill and died in 1392 at the age of 36. He was posthumously honored with the title Crown Prince Yiwen (懿文太子) by his father and Xingzong (明兴宗), Emperor Kang (康皇帝, lit. "Emperor of Health") by his son.
After his younger brother Zhu Di usurped the throne, he was posthumously demoted back to Crown Prince Yiwen. During Southern Ming, he was again posthumously restored as Xingzong and Emperor Kang.
This poem would've governed the first character of the personal names of the next 20 emperors of China, but only the first two were officially ever used. After the usurpation of the Prince of Yan Zhu Di, the Jianwen Emperor was said to have died in a fire and his surviving children were killed or kept in isolation to prevent rivals from the throne, and the younger sons of Zhu Biao were also kept under house arrest or killed. But during Republic of China, the politician Wang Pixu (王丕煦) wrote a county chronicle for Laiyang, in which it was recorded that Zhu Yuntong had many descendants there through his son Zhu Wenkun (朱文坤).
