It should be a liar exhibition. Except for the essay, the organizer didn't publish any information about the contest, including the results and settings of the awards, and didn't know the number of gold, silver and bronze awards. It is estimated that only 80% of the submissions are gold prizes and 20% are silver prizes. The organizer sent a happy newspaper to these authors, asking them to pay money to attend the award ceremony in Beijing (the cost is not low). Many calligraphers of the peasant masses saw that they had won the gold medal, and most of them had to pay for it, so the organizers made money. In addition, there are books, and the cost is also high. Your work will be printed in the book only if you pay. Exhibition of pure commercial swindlers.
In addition, you can check the gold medal works that participated in the exhibition in previous years through Baidu. These organizers don't know calligraphy at all, or have no evaluation at all. Is a calligraphy lover, as long as you vote for the exhibition, you can get the gold medal.
I advise you not to participate in this exhibition in the future.
