What was the weather like in Shenyang in June+10/October, 5438? What clothes should I take to go there on business?

Now the temperature in Shenyang is18-20 degrees Celsius in the morning and 3 degrees Celsius in the evening! But it's especially cold in the morning and evening!

You should be able to wear a sweater and coat now! You can wear less thick inside and a thicker coat. A little Mao Mao in it won't be hot. If you are hot, you can take off your coat!
