Empress Zhangsun
In 636, for reasons unknown, Fang was briefly removed from his post and returned to his mansion. When Emperor Taizong's wife Empress Zhangsun (Zhangsun Wuji's sister) died later that year, she, in her final words, pointed out to Emperor Taiizong that Fang had faithfully served him throughout his career and should not be removed. After her death, Emperor Taizong restored Fang to his post.
