And when Kebir Tumer was bedridden for years due to arterial sclerosis, the girl often kept company with her foster father and comforted him.

To ensure the girl a good life in the future, the couple had made a will to leave their property to the girl. And their four sons are supportive of the decision.

"Since my brothers and I have got married, we fully understand and are proud of the decision made by our parents," said Ahmat Kebir, one of the sons.

Now that Mairamhan's husband has passed away and the meager income of the family not enough to support the girl for higher education, the Uygur woman is looking for the girl's biological parents or foster parents who would like to adopt the girl to give her a better life.

"She will know (her identity) sooner or later... I am getting old and I am worried that if I die someday, no one will take care of her," said Mairamhan.

The Uygur woman said although she does not know why the birth parents of Belikiz abandoned her, she believe they must have their difficulties. She added, she would like to see the girl reunite with her birth parents.
