On Children's Day, my aunt gave the child a red envelope. How should I reply?

To accept, but also thank the children's aunt for her love, no matter how to say, they are all children's relatives. The most precious thing in this world is family, so that children can know how to cherish and be grateful. In the next holiday, if my aunt has a child, I can give her a gift and send some good wishes to her child, so that the relationship between the two families will be more harmonious and intimate.
