I participated in the sixth session and received a notification that I won the first prize. The call for papers said there was no charge, but after receiving the good news of the award, if you participate in the award conference, you need to pay a 980 registration fee and 2980 conference fees. The notice also said, "This competition does not charge entry fees or review fees. Voluntary participation and voluntary honorary guests will not affect each other, and certificates will be sent for free." I checked the previous invitational competitions but the results and the list of winners have not been announced. It is estimated that many people have won awards, and the organizers are taking advantage of this to make profits, so they dare not announce the results of the awards and the list of winners.
