not really,
if you live in Shenzhen and live like a local person, yes you can save alot
but if you live in Shenzhen but still needs to go to a "foreign country standard" environment for "foreign country standard" meal...it may cost the same.
another thing to concern is "security", crime
I have factory in China, but I only stay in the factory when I am in China
I know 3 persons who's kidnapped and killed in Shenzhen
Dont' get me wrong, I ve been to different cities in China,I love Guangzhou, and Shanghai.., etc..
but I do have problem with Shenzhen...I don't know what the society is made of....or just Bad things happen around me and the people I know.
