10 month 1 day, what about the sunshine?

It won't be cold, but it will be. Just wear trousers, a T-shirt and a coat. There is a great temperature difference during the day. It may be warmer to wear short sleeves at noon and long sleeves at night. Daily necessities depend on personal situation, so I can't suggest them. It's ok to wear shorts at the seaside at noon, but not at other times. It's fun not to go to the seaside, and there are many seaside scenery. Welcome friends from other places to travel in Rizhao. Finally, have fun!
