We stopped and wait for customs to check us. Toilets are closed and we have to wait for around an hour. 

Many customs employees. They check  if people are hidden in the storage area of the beds …..

Track size change. All in all the entire passport control and engineering work took 4 hours. I am hungry and are already eating biscuits form my new room mate. Lights are back on, power supply not yet working. 

Chinese border guards were welcoming us and wishing us a good journey super friendly and very efficient. 

Toilets are still closed and traveller get impatient.
