You can fly from HK to Guangdong. Then tale the airport shuttle bus to Wanjiang Dongguan. Take a taxi to the general bus station to take bus L1, you will get to the exhibition center.

Hi Mr.Tom

The best way is by train from HongKong To Guangzhou East railway station directly then by taxi to this Exhibition center

Thank you very much for your help, Mr.Jerry and Mr.Sunny.
Best Regards,

Hi, sorry to be asking for some more info:
I found that if I travel from HK to Guangzhou East Railway Station, then I have to return back to the south for about 70 km by taxi, to find the Exhibit Center. And in the afternoon I should go again north to the Station to get in the train to return to HK.
Is this correct?, Hom much time will I need to do this in the same day? Is there any better way to visit the Exhibition, is it possible to go by Ferry? Where and how is my passport controled when I enter Mainland China? Will you please give me more information? Thank you very much, best regards,
