There were many calligraphers of emperors in the Song Dynasty, and the most distinctive and recognizable one was the thin gold calligraphy of Evonne, Song Huizong. However, it is recognized that the highest level of calligraphy of the Emperor in Song Dynasty is Song Gaozong Zhao Gou. In my experience, fine gold is not suitable for logo font, because this font is too thin to look good on a flat surface. If you want to use the Emperor of the Song Dynasty, I personally suggest that you look at Song Gaozong, Song Zhenzong and Song Renzong. They are all plump.
