What's the weather like in Dalian around April 20th? I come from Sichuan. I didn't know what to wear at that time.

At that time, the weather in Dalian was basically warm, which may reach about 20 degrees, but Dalian has a maritime climate, and it will be colder when it is windy. This year, the weather is changeable. I suggest you check the weather online in advance. If the wind reaches 4 or 5, it will not be too warm. Besides, Dalian is cooler in the morning and evening. I suggest you take a thin coat. I'm afraid of cold, too. It's always cold to wear skirts on May Day. I just need a layer of underwear and a thin coat. I hope Dalian will welcome friends from afar with fine weather.
