With respect to the low Putonghua level of most Yi Nationality teachers in village kindergartens, Sichuan Provincial Education Department has commissioned provincial normal universities to carry out a training project for improving village kindergarten teachers' Putonghua level. Our study objects are 284 teachers of Yi Nationality in this project at China West Normal University in 2019, all from the village kindergartens of impoverished counties in Liangshan Yi Autonomous Prefecture of Sichuan province. In this project we explore and propose the following strategies: 1. Language experts focus on training Yi Nationality village kindergarten teachers in standard pronunciation skills; 2. Preschool education teachers focus on training them in oral language; 3. Class directors organize them to read for half an hour every morning; 4. Volunteer instructors follow and instruct them to train in Putonghua from 7:00 to 8:00 in the evening; 5. In this project the learners are encouraged to practice Putonghua with their companions in their free time.
