LOGO uses elements such as "Zhong" in the Central Plains, initials Z in Zhengzhou, cards and chips for creativity. The card planning takes the modern landmark buildings "Erqi Pagoda" and "Zhongyuan Pagoda" in Zhengzhou as the background to show the historical and cultural characteristics of the Central Plains. It is reported that ordinary cards are divided into Huang Ka and green cards, and the details may be adjusted. After that, commemorative cards, student cards and old-age cards will be issued one after another.
