Rush, a belated echo to that "Happy Mom's Day" all! I understand all 11 Chan Children [8 boys & 3 girls--in the novels that is] presented Momma Chan with a beautiful bouquet of Peony flowers and a card.
Most prominent signatures included Henry (oldest son); Rose (eldest daughter and 'the flower of his flock'), Evelyn (15 yrs), Anna (youngest daughter), and newborn Barry (youngest son) who applied a hand print!
