What to wear in Shenyang around mid-April?

Now the temperature difference between morning and evening in Shenyang can be slightly larger. I don't know how old you are. Generally, people under the age of 30 wear a coat and a small shirt under it. Now I wear a single leather coat when I go out, and sometimes it is a little hot.

Shoes and ladybugs (but I think it can freeze my feet, hehe). A single shoe will do, or a single boot ~ ~

By the way, report today's weather: 4- 15 degrees ~ ~
