thanks to Mr. Bill for his reply.

may i have additional info from anybody?

i was looking thru google and i believe 'north square of shanghai railway station' is in zhongxing road.

am i correct if i say that the south square that mr. bill was referring to is in moling road?

so from north square, i walk west till i reach henfeng north road and then turn down south until i reach moling road.

appreciate anybody's assistance. again, thanks to mr. bill as that was helpful
