Going to Beijing on 5th to 12th April. Will air pollution be bad and what attire to bring? Thanks

For the temperature, it is around 5 to 13C and it is changeable.
For clothes, you need to take a thick coat, jeans and thin sweaters. It will be dry and windy at that time.
For the air pollution, it is hard to predict, because it is really a serious problem for BJ. It is suggested to pay attention to the weather forecast before going there, so that you can get the more exact information.
