What do you mean by green mountains in the deep sea?
Blessings are as high as mountains, and good deeds are as deep as the sea. This idiom expresses the hope that the other person will be blessed and kind. I hope that the other party can accumulate great blessings, accumulate virtue and do good deeds, and the mountains are high and the seas are wide. It is not only a good wish for people, but also a yearning and pursuit for a better life.
