What calligraphy works are suitable for hanging in the office? Is painting and calligraphy better?

Xu Beihong-If the picture is well imitated, it is best to use mahogany frame or calligraphy, but it is best not to copy the calligraphy, and the banner is better, vigorous and powerful, not fragmentary. To embody the enterprise spirit and culture, it is best not to use oil painting, because there are few extraordinary people hanging in the purlin, unless it is really big, it will hurt people and make people laugh. If you use calligraphy, you can also choose the font with grass in the official script.
