Hi, since the train K952 starts from Shenzhen and it is just a pass-by train at Guangzhou train station, you can’t book it online. For the tickets, u could purchase directly at Guangzhou train station or contact some booking agencies there for arrangement. But you could book tickets on train K36/K37 online. You could submit an online booking first and they will provide you the quotation and payment details via email after receiving your booking requests. Issued tickets would be delivered to your hotel address in China mainland.
