What's the weather like in Shenyang in mid-April? What kind of clothes should I wear? Will it be cold to wear boat shoes barefoot?

It is impossible to wear boat shoes barefoot. It's very cold. It is recommended to wear beautiful and fashionable boots or ordinary shoes. Shenyang came late this winter. It is still windy in recent days. I suggest you wear a windbreaker or jacket. But good sisters can get married with a skirt and a pair of boots. Very fashionable. I am wearing it now. Congratulations to your sister, by the way.
