Ms  Jia: in Britain, according to the law on the right of eldest son inheritance, the first son born to a man's first wife has the right to inherit family property first  Mr  Chen: you're wrong
The Duchess of brown legally inherited all her father's property
Mr. Chen's conclusion cannot constitute a refutation to Ms. Jia, because he misunderstood Ms. Jia's words as that only his son has the right to inherit property.
