Zhu Biao朱標 (1355 – 1392) was Emperor Hong Wu's first son and Crown Prince of the founder of the Ming Dynasty. He was supposed to be soft hearted. He once questioned his father why many of the ministers and generals who were pioneers of the Empire were being killed or banished. His father told them they were like thorns on a vine, and he was removing the thorns before passing the vine (crown) to his son. He died in 1392 at the age of 38 before emperor Hong Wu passed away, so Zhu Yunwen succeeded Emperor Hong Wu in becoming emperor.
