Yuwen Tai
in spring 535, Gao Huan learned that around the new year 535, Emperor Xiaowu, who had a falling out with Yuwen Tai over Yuwen's refusal to condone his incestuous relationships with his cousins, had been poisoned to death by Yuwen. Gao suggested that an official mourning period be held for Emperor Xiaowu, and while there were disagreements, eventually a mourning period was held.
