I want to go Aisa to expend my holidays. pLz let me know about how i can get Visa for Asian Country?

Most Asian countries, except from Mainland China, has landing visas for Swedish passport holder.
I've been all around Asia without applying beforehand, exception Mainland China.
HOWEVER, Shenzhen has a 5 day visiting visa upon arrival.
