Hi, there are many scenic spots worthing your visit, such as Splendid China, Window of the World and Overseas Chinese Town East. You can refer to Shenzhen Tour Packages(https://www.travelchinaguide.com/package/shenzhen.htm) to plan your itinerary. Since you will have one week time, I advise you to have a side travel to Guangzhou. The 16th Asian Games(https://www.travelchinaguide.com/cityguides/guangdong/guangzhou/2010-asian-games.htm) will be held at that time. If you have interest, you can go to see it.
