I want to go to Zhengzhou on May Day ~ ~ What should I wear to Zhengzhou on May Day? Is it particularly hot? I'm from Liaoning ~ ~ ~

You can wear short sleeves on May Day, but it will still be a little cold in the morning and evening. Besides, the weather is unstable at this time, and it may be a little cold. I think you should take a thin coat in case it is cloudy or rainy. You should wear some short sleeves. If the weather is fine, it is more appropriate to wear short sleeves inside and shirts outside in the morning. If it is hot at noon, you can take off your shirt.

It depends on the weather at that time. The weather is not very stable at this time, it may be warmer than 30 degrees, or it may be cooler, about 20 degrees.
