Legal analysis: No, parents who are unable to work or have difficulties in life have the right to ask their children to pay alimony when they fail to fulfill their alimony obligations. However, if the adoptive parents of the abandoned baby legally go through the adoption procedures, then he can not fulfill his obligation to support his biological parents.

Legal basis: Article 1067 of the Civil Code of People's Republic of China (PRC) states that minor children or adult children who cannot live independently have the right to ask their parents to pay alimony. Parents who fail to perform their maintenance obligations, lack the ability to work or have difficulties in living have the right to claim alimony from their adult children.
