The research background of the paper is that the Genshin Impact has become very famous in recent years. The game made $4 billion in revenue in just two years after its launch. The game’s worldwide popularity has attracted a lot of attention. Thus, this paper wants to find out the producer uses which kind of methods to attract such many players and gain a large amount of profit. The paper uses a literature review and case analysis as research methods. By using these two methods to research, this paper finds that the producer of the game Genshin Impact uses lots of market strategies to attract players. Also, this research wants to explore how the game Genshin Impact successfully integrates traditional Chinese culture and promotes traditional Chinese culture to overseas players. The conclusion is producer of Genshin Impact uses different market strategies to attract players and help promote traditional Chinese culture to overseas people.

In the pursuit of highly efficient perovskite solar cells, spiro‐OMeTAD has demonstrated recorded power conversion efficiencies (PCEs), however, the stability issue remains one of the bottlenecks constraining its commercial development. In this study, we successfully synthesize a novel self‐polymerized spiro‐type interfacial molecule, termed v‐spiro. The linearly arranged molecule exhibits stronger intermolecular interactions and higher intrinsic hole mobility compared to spiro‐OMeTAD. Importantly, the vinyl groups in v‐spiro enable in situ polymerization, forming a polymeric protective layer on the perovskite film surface, which proves highly effective in suppressing moisture degradation and ion migration. Utilizing these advantages, poly‐v‐spiro‐based device achieves an outstanding efficiency of 24.54 %, with an enhanced open‐circuit voltage of 1.173 V and a fill factor of 81.11 %, owing to the reduced defect density, energy level alignment and efficient interfacial hole extraction. Furthermore, the operational stability of unencapsulated devices is significantly enhanced, maintaining initial efficiencies above 90 % even after 2000 hours under approximately 60 % humidity or 1250 hours under continuous AM 1.5G sunlight exposure. This work presents a comprehensive approach to achieving both high efficiency and long‐term stability in PSCs through innovative interfacial design. [ABSTRACT FROM AUTHOR]
