hi im travelling to china in few months which reasonable hotel & resturant can you recommend.

HK is connected with Shenzhen, China. From HK, you can easily find cross-border buses or mtr to reach SZ directly.
The distance between HK and BJ is around 2000km.

In China, the local express hotels such as Hanting, Home Inn and Ibis are suggested. Or the young hostels can also be your good choices.
