Lao Cai Hanoi one way

Extreme North of Vietnam.
The border with the Chinese province of the Yunnan is just few miles far.
From the small station of Lao Cai a train leaves and 12 hours after it will arrive to Hanoi, the capital of Vietnam.
After celebrating the Chinese New Year’s eve in the family home in the countryside, it’s the time to go back to their own home for hundreds of citizens of the capital.
The only way to do this journey is by train.
