What do you mean by "I only wish the world is stable, the years are quiet and good, and I often smile when I meditate"?

This is a sentence that Hu gave to Zhang when Hu Lancheng and Zhang Ailing got married. I hope they can live an ordinary life and live a stable life. This is the most heartless person, but he said the best wishes in the world. Anyway, this sentence itself and the ideal it expresses are beautiful.
