This paper reviews the Sino-US trade war, analyzing its background, evolution, and economic consequences on both countries and the global economy.

This study explores factors influencing students’ sustained use of Virtual Simulation Learning Systems (VSLSs) in Chinese higher education. Analyzing survey data from 274 students, the research finds that perceived value, driven by benefits outweighing costs, significantly impacts continued engagement. System quality and social factors, like course scheduling and teacher recommendations, also play vital roles. The findings inform recommendations for enhancing the enduring utilization of VSLSs, emphasizing the importance of quality systems and supportive learning environments.
