In contemporary times, I personally suggest that if you want to collect calligraphy works.
It is best to choose a member of China Book Association.
And it is better to be the works of calligraphers who have won the grand prize in the national calligraphy exhibition (so-called national exhibition)
Don't blindly collect calligraphy works, let alone listen to other people's deception.
Don't believe the propaganda of the media and the boasting of some people, otherwise you may suffer.
I guess you are a calligraphy lover, too?
Choosing a good writing brush is actually very important.
