How do you say that the leader personally writes couplets?

Leaders who personally write couplets should give thanks and appreciative replies. Appreciate it according to the font used: if the running script is natural and smooth, the regular script is dignified and generous, the official script is goose-tailed, and the cursive script is wild and uninhibited, then look at the three elements of calligraphy: strokes are like people's five senses, structure is like people's height, and composition is like people's clothes. In a good way, praise the leader for his good writing and express his gratitude.
