Liu Hu (劉虎) (died c.November 341[1]), also known as Wulugu (烏路孤), posthumously named Emperor Jing (景皇帝), was a Tiefu-Xiongnu chieftain during the Sixteen Kingdoms period.
Due to Tang dynasty naming taboo, he is referred to as Liu Wu (劉武) in the Book of Jin.
Following Gaoshengyuan's death in 309, Liu Hu succeeded him and founded a tribe he named the "Tiefu" (鐵弗), a word used to refer to people with a Xiongnu father and a Xianbei mother.
[5] Liu Hu fled west to Shuofang Commandery by crossing the Yellow River and offered his submission to the Xiongnu-led Han Zhao state.
[9] After Liu Hu's great-grandson, Helian Bobo established Xia in 407, he was posthumously honored as Emperor Jing.
