Yao Ce has lived with his adoptive parents for more than 20 years. They have always been father and son. So legally speaking, even if Yao Ce is not their own child, it is also a de facto adoption relationship. Moreover, their adoption relationship began at 1992, before the adoption law and the latest Chinese Civil Code were promulgated. Neither the Adoption Law nor the Civil Law can be traced back, so their de facto adoption relationship can be legally recognized.
Since Yao Ce and Min Xu are adopted, they are adopted mothers and adopted sons, Yao Ce has the right to inherit Xu Min's property. If Min Xu asks Yao Ce for their only property on the grounds that he is an outsider, there may still be legal problems in the mother-child relationship between Yao Ce and Min Xu, and the court may not necessarily support Xu Min's request.
In addition, the possibility of Guo Wei returning to Jiangxi is slim. Guo Wei has lived in Henan for more than 20 years. He is married and has children. He is from Henan. Even in ancient and modern times, it is rare for such biological children to return to their parents after many years. Guo Wei has been living a quiet life in Henan. He probably doesn't want his life to be disturbed. There is almost no possibility that Guo Wei will return to Jiangxi.
After the adoptive mother and adopted daughter are dissolved by the court, they can restore the relationship between husband and wife and inherit the inheritance.
