In my opinion, it is not appropriate to hang ordinary China paintings and calligraphy. Advertising companies are places that reflect creative value, and works that are too abstract are not the first choice. Calligraphy should be based on inspirational Mohist works, which can be recognized by most people, but it definitely has artistic aesthetics. Chinese painting I prefer the works of horses which are abstract and tense. I haven't studied western painting, but I think it will be more attractive to add some artistic sculptures and reliefs.
