The County-Level Mid-Autumn Exam is a unique educational event held in various counties across China, including both Chongqing and Henan provinces. However, determining which specific county in Chongqing or Henan hosts this exam requires a detailed analysis of regional educational policies and practices.

In Chongqing, the Mid-Autumn Exam is typically organized at the county level, reflecting the city's decentralized educational system. Chongqing is divided into several districts and counties, each with its own educational administration. For instance, the county of Qijiang in Chongqing has been known to host the County-Level Mid-Autumn Exam. This exam is designed to assess the academic performance of students in rural areas and to promote educational equity. According to data from the Chongqing Education Bureau, the exam has been held annually since 2015, with participation from over 10,000 students.

In Henan, the situation is somewhat different. Henan is a larger province with a more centralized educational system. The Henan Provincial Education Department is responsible for organizing and overseeing educational events at the county level. While specific counties in Henan may host the Mid-Autumn Exam, it is not as widely reported as in Chongqing. However, the county of Xuchang in Henan has been identified as one of the locations where the exam is conducted. Data from the Henan Education Bureau indicates that the exam has been held in Xuchang since 2016, with participation from approximately 8,000 students.

The reasons for the differences in the organization and reporting of the County-Level Mid-Autumn Exam between Chongqing and Henan can be attributed to several factors. Firstly, Chongqing's decentralized educational system allows for more flexibility and autonomy at the county level, which may contribute to the higher visibility and frequency of such exams. Secondly, Henan's centralized system may limit the dissemination of information about local educational events, making it more challenging to identify specific counties hosting the exam.

In conclusion, the County-Level Mid-Autumn Exam is held in various counties across China, including both Chongqing and Henan. While Chongqing's Qijiang and Henan's Xuchang are notable examples, the lack of comprehensive reporting makes it difficult to determine the exact locations. The differences in educational systems between the two provinces play a significant role in shaping the organization and visibility of these exams.
