1. Location: Kashgar is remote and the transportation is inconvenient. Students may come from rural areas around the city or further away. In order to receive education, they need to board at school.

2. Uneven distribution of educational resources: Due to the influence of geographical conditions and economic development, some rural areas may lack sufficient schools and educational resources. In order to solve this problem, the establishment of boarding schools can help provide educational opportunities and improve students' learning conditions.

3. Characteristics of ethnic minorities: Kashgar is mainly inhabited by ethnic minorities such as Uighurs. Due to cultural differences, language barriers and other reasons, some students may choose to receive education in boarding schools in order to obtain a better learning environment and opportunities for cross-cultural communication.

4. Education reform policy: In order to improve the quality of education and popularize education, the government may have implemented a series of education reform policies, including building and supporting boarding schools.
