司馬孚
Sima Yi had one elder brother, Sima Lang (Boda), and six younger brothers (in decreasing order of seniority): Sima Fu (Shuda), Sima Kui (Jida), Sima Xun (Xianda), Sima Jin (Huida), Sima Tong (Yada), and Sima Min (Youda). The eight Sima brothers were collectively known as the "Eight "Da"s" because their courtesy names all ended with "da" ().
