Hello, I am planning to travel to Hong Kong through Shen Zhen during Chinese New Year (early February). I will be taking the train from Beijing to Shen Zhen (arriving around 8:00PM), and then need to go to Hong Kong via bus or train. Could you recommend the best way to travel from Shen Zhen to Hong Kong at this time? I am concerned that bus or train tickets may be difficult to get during the holiday season. Thanks for your help!
