Dear D. Lee,
Thanks for contacting Top China Travel!
We are in-bound China tour operator, so we can help you with Shanghai, Xian, Beijing, Guilin, Hong Kong tour. But for Seoul, Korea tour, we do not orgnize that, and you might have to find local travel agent in Seoul to orgnize that for you.
There are some bus group tour with daily departure in Shanghai, Beijing, Guilin and Hong Kongm then we can combine the daily bus tour for you to make it a tour package. But could you please advise us some more details of your trip plan first?
1) Could you please tell me your tentative arrival date in China?
2) Would you like us to include hotel in the tour package, or you will book it by yourself? If you need us to include it, What kind of hotel would you prefer to stay in during the trip? 5 star for deluxe hotel? 4 star for first-class comfortable hotel or 3 star for budget hotel?
3) Which city will you start your China tour? And which city will you end the tour in China?
Any further request or question, please feel free to contact with us.
