Portrait painting from 1360 showing the Chinese Muslim general Chang Yuchun of the Hui people. He was a follower of the Ming Dynasty's founder, Zhu Yuanzhang (Emperor Hongwu, r. 1368-1398) , and contributed greatly to the founding of the dynasty. Chang was famous for his bravery and formidable prowess in battle, which earned him the nickname of 'Chang Ten Thousand', because he was said to be as effective as a force of 10,000 men.
