What will the weather be like in Qingdao at the end of March? How much is appropriate to wear?

The weather in Qingdao is windy, so many people feel colder, especially in the northeast. Because the northeast is very cold, but the wind is very small, so they spend most of their time indoors. By the end of March, they should wear more clothes outdoors. Anyway, in April last year, they were still wearing shirts and coats, which were thick, mainly windproof clothes. I can only help you so much, good luck ~
