In recent years, many children at home and abroad have shared their growth with their "big friend" Xi Jinping through letters.

  "Happy holidays to children across the country", "I hope you will keep your thirst for knowledge and your interest in exploration", "Welcome to Beijing on the China-Laos Railway as soon as possible", "Welcome to China to see"... The reply letter from "Grandpa Xi" is full of earnest teaching and earnest exhortation, sending blessings and conveying care.

  How did the children feel when they received the reply from "Grandpa Xi"?

What do they want to say to "Grandpa Xi"?
