Cologne

 There are less colored people in Germany than in the UK.
Some of them speak in their own languages even though they are in Germany.


A man drew a paint on the ground.
He displayed his portfolio.
If he drew in Japan, the police would come. 

At the city center, ancient Roman street was shown
and it's allowed to walk on it.

It was the first time to see and walk on rotation bridge
for boats on river Line to go through.


The railway of Germany is much better than that of the UK.
To know exact point where coach stop is easy
and a lot of trains are on service.
I can't find any advantage of the UK compared with Germany. 

Because I'm a engineer, I was always looking at anywhere mechanical things.
It' a kind of disease I think.
