What are the general routines for buying and selling calligraphy and painting?

Take the rich second generation Xie of Wafangdian as an example. Xie fictionalizes himself as a rich second generation family with many enterprises, and the collection family has many collections in the art museum. He lied that he was a great disciple, an art curator, one of the top ten outstanding young people, a deputy to the National People's Congress, exaggerating the value of the calligraphy and paintings he sold, and falsely claiming that the calligraphy and paintings he sold were guaranteed! Cheating trust is based on the above beautiful lies, selling fake paintings and selling expensive paintings! Second, Xie set up "Tuo" to raise the painting price, which will touch your enthusiasm for buying, and will make Tuo privately add you WeChat to lure you to buy paintings as a cover to buy the paintings you bought from Xie!
