Xi 'an left for Xi 'an on May 4th. What is the local weather like there?

It rained the day before yesterday. It was sunny these two days, but it got cold after the rain. Xi 'an has a large temperature difference in the morning and evening, and the highest temperature difference in summer is 15 degrees. At present, locals are basically short-sleeved, and it is a bit exaggerated to add long-sleeved or medium-sleeved jackets in the morning and evening of autumn. Just bring a thin coat.
