I'm going to Xiamen on April 20th. What do I need to wear? What should I pay attention to? Is there a big temperature difference between morning and evening?

There is a great temperature difference in Xiamen. It's sunny during the day. Just wear a short-sleeved skirt or something. Remember to bring an umbrella and sunscreen. The sea breeze is strong at night, and it will be cold. You need to wear a cardigan or scarf. If the weather is warmer in those days, you can take sandals and swimsuits to play on the beaches of Gulangyu, Baicheng and Yefengzhai. The weather is fine ~ by the way, if you are afraid of mosquitoes, you can bring anti-mosquito water.
