Travel to Shenzhen on April 28th. What is the weather like there? What should I wear?

Well, it's ok to wear T-shirts, shorts or summer pants on cloudy days, but according to the weather forecast on the 28th, it's ok for everyone to bring a coat. It's still chilly when it rains, just like it didn't rain today, but it's a little cold on cloudy days, especially at night.
