Is the official script font a free commercial font?

Official script is suitable for commercial fonts for a reason. Many shops advertise to make fonts bigger and more conspicuous. Many fonts look bad when they are big. If the strokes of a word are raised and pressed, the font looks weak and has no momentum. Only the calligraphy features of official script "Silkworm Head and Wild Goose Tail" are more suitable for enlargement, and the structure of official script is stable, so general shops use official script to write signs and advertise.
