Why doesn't Pudong stop classes?

The education department decided. According to the announcement of official website of Pudong Education Bureau, due to the typhoon, classes in Pudong Nanhui New Town, Shuyuan, Mudeng, Vientiane, Chongming, Fengxian, Qingpu and Jiading were suspended for half a day on the morning of September 15, 2022, while classes in Songjiang, Jinshan and Baoshan were delayed for two hours. The reason for not announcing the suspension of classes in the whole city is the decision made by the education department in combination with the weather forecast, aiming at the areas affected by typhoons.
