Zhu Yuanzhang decided to join the army through divination.

Tang He, Zhu Yuanzhang's partner who herded cattle when he was a child, also joined the Red Scarf Army. According to Zhu Yuanzhang's memoirs, Tang He wrote to Zhu Yuanzhang asking him to join the Red Scarf Army and Guo Zixing's men. After Zhu Yuanzhang hesitated, he made a divination in front of the Buddha. Inspired by the gods, he left the temple to end his monastic life and formally embarked on the road of the army. This is the most important turning point in his life, and this departure has completely changed his career.
