With the boom in private education，increase in small innovative schools and the expansion of online education industry in recent years，there has been an exponential rise in the turnover of principals and teachers in China's public schools. The departure of famous principals and teachers from public schools has led to online debates and in some places even triggered mass incidents. There are many reasons behind this phenomenon，such as teachers' low income，lack of autonomy in teaching，pursuit of an ideal education，and longing for a better life .The phenomenon is an indication that profound changes have taken place in China's society and education，and the education system urgently needs a more profound reform. Possible solutions are suggested，including： increasing teachers' autonomy in teaching，giving principals full autonomy in running schools，promoting the professional development of teachers，and creating multiple incentives for teachers.
