Written on those cards are such letters of different calligraphic styles as "Congratulations to you on November 16" and "Happy Mother's Day" with beautiful bouquets and flowers depicted in a splendid way, which show the children's mind to congratulate their mothers.

Some of the cards carry the musical notes of song "Thought of Mother" and the words of "I Love My Mother" in reflection of deep respect for the mothers who have brought up their children to be faithful to the Party and the country.

Some of them depict the looks of a happy mother with her dear child in her arms and children singing songs to congratulate their mothers.
