Someone in Heyuan writes calligraphy for tourists to sell. Is this calligraphy worth so much money?

We can't generalize. But on the whole, it's not worth that much money.

The truly valuable works are all by famous artists, but how can famous artists set up stalls here?

I also noticed in the scenic spot that many so-called calligraphers are titled as China, International, China and Global, but they are all nonsense. China Calligraphers Association (note: Calligraphers Association, not Calligraphers Association) is the social group with the highest gold content in China, and calligraphers associations in other provinces and cities. Besides, most of them are dirty.
