Features: At the time of the publication of this "Question Dictionary," as editors, we have much to say to our readers. As the saying goes, "mathematics is a gymnastic for the mind" and "a game for the intelligent." Without a doubt, various mathematical competitions (ranging from the International Mathematical Olympiad to regional events) have nurtured countless teachers and students. The role of extracurricular mathematical activities in inspiring interest in learning mathematics and improving problem-solving skills is not optional but essential in China's basic education. For this reason, over the past few decades, including mathematical competitions and other extracurricular mathematical activities, have been widely welcomed and supported by teachers, students, and parents. As early as the 1950s, the older generation of renowned Chinese mathematicians, represented by Professor Hua Luogeng, placed great emphasis on cultivating outstanding young talent and advocated and organized numerous mathematical competition events, attracting a large number of mathematics enthusiasts. In 1981, the "National High School Mathematics League" was initiated by the Chinese Mathematical Society. This popular mathematical competition was well-received by middle school teachers and students across the country and was also recognized and supported by educational administrative departments, various science and technology associations, and people from all walks of life. In addition to serving as a popular extracurricular mathematical activity, the "National High School Mathematics League" is also linked to the "National High School Mathematics Winter Camp," serving as a selection mechanism. It is well-known that the problems in various mathematical competitions are mostly prepared by experts and experienced teachers with specialized knowledge and extensive experience. Therefore, in terms of the quality of the problems, whether in terms of depth or flexibility in solving, they far exceed the exercises students normally do. For the past years' questions of the "National High School Mathematics League," after careful review, we have strived to provide as many practical solutions as possible to help readers broaden their thinking. For more challenging problems, we provide original solutions, starting from the point of entry, to clarify the source of the thought process, thereby achieving the effect of "generalizing from one to all." We pay particular attention to passing on correct thinking methods to readers rather thaning them with advanced concepts, enabling readers to achieve genuine improvement.
