The rapid popularity of card culture among primary and secondary school students stems from two main factors: firstly, it satisfies children's curiosity and desire to explore new things; secondly, it possesses unique social attributes. Cards serve as a medium for entering shared interest circles, allowing children to experience fun and a sense of accomplishment while unpacking and collecting cards. Furthermore, they enable them to build deep friendships through communication and sharing with other children. Therefore, branded trading cards have become "social artifacts" in children's hands, providing them with a sense of belonging and identity within their social circles.
The design and sales methods of trading cards inherently possess addictive characteristics. They combine aesthetic and competitive functions, and are categorized into different levels based on rarity. Generally, the rarer the card, the higher its attack power and the more exquisite its artwork. Before opening the package, the buyer doesn't know what cards are inside, or if there are any rare cards. Thus, each unpacking is like embarking on an unknown adventure; as long as one sets out on the journey, there is a chance to obtain treasure, even if the probability is slim-the probability of finding an extremely rare hidden card is as low as 0.05%-which only serves to highlight the owner's achievement.
