What kind of dress is suitable for the weather in Beijing in the morning and evening (April 15, 2o15-No.2O)

The temperature in Beijing has changed a lot in recent days. For example, on Sunday, April 12th, there was a gust of six winds, and I wore thin wool pants and down jackets. Yesterday, it was sunny again, so I just need to wear a pair of pants and two singlets. It's warm in Beijing today, too. It is said that the highest temperature is 25 degrees. Anyway, people wearing short sleeves were seen in the street at noon. It is said that there will be a strong wind (level 5-6, gust to level 7) from tonight, with a temperature drop of 5-6 degrees and a local drop of 8-1 degrees, so I suggest you take a thin down and scarf. If you have less outdoor activities, you can take single pants. If you want to do outdoor activities, you'd better take long pants. Those who are afraid of the cold should bring thin wool pants and sweaters. However, we should also prepare some singlets or vests to wear when the temperature rises. In short, bring more clothes in winter and spring. Many people have caught a cold because of the changeable weather, so it is best to take some cold medicine, Banlangen and the like to prevent it.
