How to write elders on the back of a wedding red envelope

Congratulations format on the back of the wedding red envelope: First of all, the words of blessing should be written in the middle, the name of the couple should be written in the upper left corner, and the name of the giver should be written in the lower right corner. Secondly, in terms of format, there are two ways to write horizontally and vertically. In ancient times, it was written vertically, but now most people are used to writing horizontally. But like calligraphy, older elders may prefer to write vertically. Finally, the name of the bride and groom can be written or not, and the position of the signature is different. The lower left corner is written vertically and the lower right corner is written horizontally.
