Jin De-nian calligraphy price quotation

I haven't heard of this person, so I'm ignorant. Personally, I suggest that if you want to collect calligraphy works, you'd better choose the works of calligraphers who are members of China Calligraphy Association, and it's best to collect the works of calligraphers who have won the grand prize in national calligraphy exhibitions (so-called national exhibitions). Don't blindly collect calligraphy works, let alone listen to other people's bluff, and don't trust the media's propaganda and some people's boasting, otherwise you may suffer.
