Bangkok is alluring travellers, why?
the biggest city in Thailand still leaves Asian nostalgic atmosphere , while it is economically developing and infrastructure is modernized at satisfactory level for them.
And, Thailand has no diplomatic disputes except for Cambodia. It makes the country safe and doesn't give foreigners bad impression on Thai people.
London and Paris, the second and third city, still keep their positions as world's cultural and fashion centers.
Japanese, especially Japan's girls, have impression that Europe has sophisticated and romantic culture.
When it comes to me, I would like to go everywhere I have never visited. But, the cities with rail systems are preferred.
