What to wear to Qinghai Lake in July?

July is the most beautiful season in Qinghai Lake. It's more than 20 degrees during the day, so you can wear short sleeves and strong ultraviolet rays. If you are afraid of the sun, wear thin long-sleeved clothes. It's cool in the morning and evening, so you can bring a thin sweater or coat. The weather is dry, drink plenty of water. It is best for several people to charter a car around the lake and see the most beautiful scenery.
