A widely-circulated story about a private school that makes its low-scoring pupils pay cash to more successful students has generated controversy.
Fees range from 200 to 500 yuan ($30 to $75) and are handed over to those with good grades. According to viral social media posts, the money is collected forcibly by teachers, and those who fail to turn in money on the requested day are threatened with expulsion.
