The loss of high-quality students and teachers, as well as the dilemma of the county, is the result of the comprehensive action of many factors, rather than a single natural evolution. The following are some main factors that may lead to this situation:

1. Economic development gap: Compared with developed areas, some counties are economically backward and lack better employment and development opportunities, which leads to excellent students and teachers tend to choose places with more development potential to work and live.

2. Insufficient educational resources: Some counties are relatively lacking in educational resources, including educational facilities, teaching equipment, teaching materials, etc., which cannot provide a good learning and education environment and also affect the loss of high-quality students.

3. Difference in treatment and welfare: The salary and welfare of teachers in some counties and districts are relatively low, and the welfare conditions are relatively inferior to those in cities or developed areas, which makes some outstanding teachers choose to leave counties and districts to seek better job opportunities and living conditions.

4. Educational system and mechanism: Some counties have imperfect or unreasonable educational system and mechanism, such as poor promotion channels and unfair evaluation of professional titles, which may also lead to the loss of excellent teachers.

5. Social development and cultural environment: Social development in some areas is relatively backward, and the cultural environment lacks vitality, which will also affect the retention and attractiveness of students and teachers.

The benefits of having high-quality students.

1. Improve the quality of education: High-quality students often have high learning potential and academic ability, and learning at school will promote the overall level of the class. They study hard and actively participate in classroom activities, which has a positive impact on the teaching quality of teachers and the overall education level of the school.

2. Promote academic competition: The existence of high-quality students will encourage other students to study harder and form a positive academic competition atmosphere. Students learn from each other, learn from each other and encourage each other, which makes the overall learning atmosphere of the whole class and school more intense.

3. Promote teaching innovation: The curiosity and creativity of high-quality students in learning have stimulated teachers' innovation in teaching methods and contents. Teachers will pay more attention to the application of personalized teaching, heuristic teaching and other teaching methods to meet the needs of these students, thus promoting the improvement of the overall teaching level.
