It feels hot and sometimes even like being in a smelter under the sun during the daytime. On the contrary, a little breeze would make you feel cool and comfortable. You'd better bring some summer clothes there. Besides, a pair of jeans is also necessary for you to keep away from the cold at night.
Hope it helps. Candice Song Replied on 2012-04-26
