What would a new comer like and dislike about your town

What would a new comer like and dislike about your town?
Recently one of my friends will move to Shanghai from New
Zealand and she asked me which aspects she might not adapt in
Shanghai. I think that it is as follows:
Firstly, she may think that the air pollution is very severe in
Shanghai. As everyone knows that New Zealand is a developed
country known for its beautiful natural environment. There are
fewer industry plants in New Zealand than in Shanghai. So New
Zealand is a very clean and beautiful country, just like a garden.
However, in Shanghai the air pollution is still out of control. When
you come back home from your company every day, you will find
that your shoes are covered with dusts.
What is more, my friend may find that the streets in Shanghai is
very crowded with traffic. The population of Shanghai is 13
million, which is much more than that of New Zealand. She might
find uncomfortable traveling in the streets of Shanghai During rush
hours.
Finally, I think that she may complain about some other small things
about Shanghai. For example suppose she walks on the pavement
and will find that there are too many bicycles parked on it which
block the sidewalk. Sometimes she has to walk on the street. I think
having lived in New Zealand for a long time, these small things in
Shanghai may bewilder her.

In a word, I think that my friend will dislike the air pollution,
crowded transportation and other aspects of Shanghai. As a
Shanghaiese, I think we all should try our best to make Shanghai a
better place to live in the future.
