Yang Xuangan
Yang Xuangan (楊玄感 "Yáng Xuángǎn") (died 613) was an official of the Chinese dynasty Sui Dynasty. He was the son of the powerful official Yang Su, and, as he knew that Emperor Yang was apprehensive of his father, was never quite secure. In 613, when Emperor Yang was attacking Goguryeo, he rebelled near the eastern capital Luoyang, but was soon defeated. He ordered his brother Yang Jishan (楊積善) to kill him, as to not fall into Emperor Yang's hands.
