宋辟公 / Duke Pi of Song
宋辟公 / Duke Pi of Song appears in 《资治通鉴·周纪》10丨 以家族单位 有蚂蚁吃大象的精神（1） as the successor after 宋休公 dies in 373 BCE. The source gives Song Xiugong’s personal name as Song Tian before the succession.
His source role is a compact annalistic notice inside 周烈王’s early reign. It continues the 宋国 branch already tied to Shang-remnant legitimacy.
《资治通鉴·周纪》10丨 以家族单位 有蚂蚁吃大象的精神（2） adds Song Pi Gong’s death and the accession of his son 宋剔成. The episode does not develop a separate Song political story; it keeps the notice as part of the compact Zhou Lie Wang sixth-year succession cluster.
