Qian Hongzun was born in 925. He was the fifth son of his father
Qian Chuanguan, His mother was Qian Chuanguan's concubine Lady Fu. While he was ranked as Qian Chuanguan's fifth son, traditional histories heavily implied that he was the first-born in terms of Qian Chuanguan's biological sons, as they emphasized that Qian Chuanguan and his wife
Lady Ma were sonless and that, therefore, Qian Chuanguan was sonless into his 30s because Qian Liu had forbidden officials from taking concubines, until Lady Ma personally pleaded for an exemption for Qian Chuanguan due to that reason — and listing Qian Hongzun among the biological sons born from Qian Chuanguan's concubines, while omitting his older brothers Qian Hongzhuan (錢弘僎), Qian Hongxuan (錢弘儇), Qian Hongyou (錢弘侑), and Qian Hong'an (錢弘侒), although only Qian Hongyou was explicitly stated to be an adoptive son and explicitly stated to have the birth name of Sun. (After Qian Hongzun's death, his father would (at least in words) consider the possibility of passing the throne to a member of another branch of the Qian clan before affirming the heir status of Qian Hongzun's younger brother
Qian Hongzuo, further suggesting that he did not consider his four older sons to truly be members of his clan.) == During Qian Yuanguan's reign ==
