Ok so- He xiaoman is the wife/mother in the Lu family? They sent her to the countryside to be raised by a grandma? I assume maternal <non Lu family> side Now they [cause of the real Lu daughter] want to move the family that raised the "real Lu" daughter to a nice place ...and she seems to question why the actual daughter of said family is at the place??? ...and from the description, she really gonna be part of a super family, not just the Lu family somehow.... And i assume a genius, since i bet she made the foldable bike...
