The claim was rejected because Su Li was not the biological mother, had already divorced Tang Yuanxiao, and therefore lacked the standing to sue. The court ruled to dismiss the case in accordance with legal procedures.
Even if Tang Yuanxiao and Little Tang Mo were not biologically related, Su Li still didn't meet the criteria for guardianship because she was single and still too young.
Tang Yuanxiao was unwilling to give up guardianship. Even with Mrs. Tang's history of abuse, his rights couldn't be forcibly revoked, since Little Tang Mo was the child born during his marriage to Cui Yun.
He had the means to provide for the child and had never done anything to harm Little Tang Mo himself.
When Su Li received the notice of rejection, she had just been in high spirits.
Just as she had hoped, Little Tang Mo's condition was genuinely improving.
