cab is cheap there.(maybe for the local it's luxury, but for
you, it's cheap.)
Shenzhen got the "shi jie zhi chuan", a park with mini size of
attractions around the world. like Mini of statue of liberty, white
house, ivory tower etc.
Got the "hang kong mu jian"(aircraft carrier) opened for public to
see.
but i not interested in those things.
The food in shenzhen is quite similar to HK. Cha can ting can be
found easily in shenzhen, but not in northern cities of china.
Maybe you want to try to eat some expensive seafood there, cheaper
than sg. I went to eat seafood with 3 other fren, got big lobster,
got "xiang ba bang"(the elephant trunk like thing), oysters, big
prawns, and some other dishes. 800RMB. Convert to sg sure not enuff
to eat so many good stuff.
