Is it true that WeChat sells calligraphy live?

It's fake.

Many famous calligraphy and paintings are imitations, and famous artists will not sell calligraphy and paintings on them;

They have special agents in charge and will not sell them everywhere;

If this painting is true, it must not have been painted by a famous painter. Basically, it is some general-level commercial works, which are only suitable for home decoration. There are very few creative calligraphy and painting with artistic value.
