Answer:
In every way possible. In a repressive society, like China, the arts are limited by laws and this is a reflection of that society. In a free society, like the US, the arts reflect that freedom. The content of the arts, films, music, dance and so on, is a reflection of the society. For example, if the society is violent, the content of the arts from that society are likely to be violent. The opposite is sometimes true too, and this reflects a countercultural movement in the arts.
