Is the teaching staff of Bosch Lean Country Garden Foreign Language School strong? Is the teacher stable?

My niece is studying at Boschler Lai 'an Country Garden Foreign Language School. She sent her children there because the teachers there were very strong. The voluntary turnover rate of teachers in their school last school year was less than 10%. School management cadres and backbone teachers are selected by Bosch Music Education Group and have been recruiting outstanding teachers for the whole country. The school also attaches great importance to the cultivation of teachers' professional quality and teaching ability, and often sends them to the headquarters for study and training irregularly. I was relieved that my relatives left the children with me there.
