婆雌子部 (婆 has the fanqie: 蒲 + 賀 [pó/pò]. In Chinese this is the Vātsīputrīya [Calf-Son school]. Formerly called 跋私弗多羅 [Vātsīputra]. In ancient times there was an immortal named 跋私 [Vatsa]; the mother was of this immortal's lineage, hence her surname was Vātsī. An arhat was the son of this woman, and took his name from his mother. It emerged from the Sarvāstivāda school.)
