In Panghsan, which hosts the headquarters of United Wa State Army, in the Wa self-administered zone, most pupils use the Chinese language.
Around 300 children studying at the Panghsan Basic Education High School (BEHS) use the Myanmar language. The Ministry of Border Affairs funds the school.
However, between 800 and 1,000 pupils attend several Chinese-language schools.
The Panghsan BEHS exams are held in Tant Yang, 100 miles away.
