I plan to have one day trip to shenzhen with family. The main destination is see torra, window of The world and finally shopping prior return back to Hongkong. What's your suggestion?

Would you clarify the Torra in your question? Anyway, I sugegst you visit Window of the World and maybe Torra in the morning. After lunch, take local subway Luobao line to Laojie to Dongmen Pedestrian for shopping.

No need to rent a taxi at all. The public transportation in the city is convenient and you will mostly walk for visit and shopping. Anyway, I just know the rental fare for a car is CNY350-400 per day.

Thanks for your suggestion. I mean is terracotta and horse museum exibition

Oh, I see. You may refer to the Terracotta figures exhibition at local Minsk World. Well then, you'd better go to Window of the World in the early morning and then go to the Minsk World for a visit. In the afternoon, time is sufficient for shopping.
