I will be visiting Shenzhen from 6 to 9 July 2016 and will be staying in Luohu District.

It will be cloudy, and shower sometimes. The temperature may range from 80F to 85F at that time. It will be quite hot. You may pack T-shirts, dresses, shorts, sandles and other summer clothes.

For shopping, you can go to Dongmen Pedestrian Street. Take Luobao Line from Luohu Station to Laojie Station, Exit E, and you can see it.
For sightseeing, you can take metro Luobao Line to Window of the World Station. Then, you can see the Window of the World, the nearby Happy Valley and Splendid China. Have fun! :)
