What language does my sister use to give my sister-in-law a red envelope on her birthday?

Language blessings that a sister can send to her sister-in-law's birthday red envelope include but are not limited to:

1. Happy birthday to your brother-in-law. Your kindness makes the world a better place. May this day that belongs to you bring you happiness, and may the future days be icing on the cake.

Only those who know how to live can appreciate the beauty of flowers, and only those who know how to love can appreciate the fragrance in their hearts. I wish my brother-in-law a special birthday.

Just like roses are lovely, may your birthday bring you happiness, because you are the cutest sister, and I wish your brother-in-law a happy birthday. The above contents all express my best birthday wishes to my sister-in-law and my longing for a better life, so it is very appropriate to send a verbal blessing.
