Chinese authorities have suspended a teacher after she was recorded berating her students for not providing teachers with gifts.
Many parents in China's hypercompetitive schooling system use gifts to try to buy influence.
The teacher, Feng Qunchao in Northeast China's Heilongjiang province, harangued the high school students throughout the class.
"You don't take this seriously, huh?" she says, according to an audio tape. "Can't afford two or four dollars? You guys are a bunch of trash! A bunch of dog lungs," she adds, using a Chinese insult.
