Translation:His home is in China.
Because 他 is "he, him", so 他的 is "his". 她 is "her, she", so 她的 would be "hers". But both have the same pronunciation "tā".
From the Oxford Dictionary -
home: the place where one lives permanently, especially as a member of a family or household; the family or social unit occupying a permanent residence; etc.
house: a building for human habitation, especially one that consists of a ground floor and one or more upper storeys; the people living in a house; a household; etc.
While they sometimes point to the same thing, "home" isn't equal to "house."
