On Oct．21，Harbin Education Bureau decided to close primary and junior high schools for two days．

??? Beijing started a program on Oct．22 which has a warning system with four levels．The red warning is the highest warning level．It means that the next three days will see serious pollution．

When a red warning is issued（发布），schools will close．

If there's pollution that's not as serious，the Beijing Commission of Education will ask schools to stop PE classes and outdoor activities．
