I arrive in Guangzhou Airport at 06:15 AM and leaving at 09:30PM. How and where do I have to go ?

As you have more than 10 hours' layover in Guangzhou, you can make use of this period of time to explore the city a bit. The recommended places for sightseeing you may consider are Yuexiu Park, Dr. Sun Yatsen's Memorial Hall, Shamian Island. As for shopping, you can go to Shangxia Jiu Lu Pedestrian Street or Beijing Lu, which are the popular commercial pedestrian streets filled with a variety of shops and restaurants.
