Am going to Guangzhou by April 3-7, what is the appropriate clothes to wear during these days?

The temperature may range from 70 F to 85 F in the early April. It will be cool and moist. Although there may have several showers, it won't influence the sightseeing a lot. About the clothes, you can prepare jackets, thin sweaters, long-sleeved shirts, jeans, pants and sneakers.
