Hi, my name Janah from Indonesia, we are planning to travel to shanghai, Shenzhen and Hong Kong in December.

From Shanghai to Shenzhen, two trains T211 and T101 are operating daily. Since train tickets are always under great demand, you would better purchase the tickets online in advance. From Shenzhen to Hong Kong, no trains are available. But you could pass through the Luohu port and take the MTR directly to the centre of Hong Kong.
