I've found, from decades living in Hong Kong, that very few Chinese can pronounce my surname. They tend to coalesce the -dg- into a kind of guttural glottal stop. Mind you, in my home town in England, where Hodgson is the third most common surname (after Wilson and Thompson), the tendency is to omit the -g- altogether, which is how I pronounce my name (but only because that's what I was taught by my parents, reinforced by how I was addressed by friends, neighbours, teachers, etc. The former England football manager's name is usually spoken with the three consonants -dgs- all pronounced (as is mine if I'm introduced by someone from the south of England).
A few years ago, I posted
an article on my blog about the pronunciation of place names that was mainly a complaint about the way the BBC treats pronunciation nowadays. However, it also included a quiz on the pronunciation of English place names (source: a booklet produced for the BBC by an advisory panel in 1936) that you might like to try. You will be doing well if you get more than two right out of twelve!
