Is the calligraphy of silk cloth better or the painting more valuable?

Consciousness is calligraphy or painting in silk, which is valuable.

If so,

First of all, writing calligraphy with silk is not effective, and it can't be compared with rice paper. Many technical things of calligraphy cannot be expressed, so its use is limited.

Silk can be used to draw Chinese paintings, but it should be brushed with alum water and coated with glue as needed.
