Food: Beijing roast duck is very populay.

Thanks a lot Mr Chang, we are looking forward to going around china. Please forgive me for another favor, can you suggest a location of hotel in shanghai where we can readily access transpo to the F1 race circuit and also near to the meet up points of seat in coach tours in shanghai. By the way we are planning to join seat in coach tours to minimize our travel costs. :)

Hi, Mrs Aileen, coach tours to where? For F1 race circuit, you had better stay close or with easy access to Subway Line 11. For easy transportation to the airport, city center, Bund and shopping area, I think it is better to stay along Subway Line 2. I have no idea about the destinations of your coach tours, so, I don't know the meet up points then.
