If the typesetting of the wedding blessing red envelope is horizontal, write from top to bottom; If the vertical version is written from top to bottom, from right to left. If you know the name of the bride and groom, you should write it, and sign it with your full name. It is not recommended to write a message that is too long. The message can be "Congratulations to you, wish you sweet honey, 100 years of good luck!" Or "flowers and candles smile to greet the wingbirds, the bridal chamber is happy to open and the first plum." This kind of blessing.
