The Hualian Dasha is one of the landmarks of Shenzhen located along the Shennan Zhong Lu(深南中路). It is also called Bell Tower, since there is a large bell on its top. Just at the foot of the buidling, it is the Kexueguan station of Shenzhen subway Line 1, the terminal of which is Shenzhen Railway Station.

I found a map here: http://www.maps-of-china.net/city/shenzhenm.htm
the names are somewhat different: Hua Lian Da Sha->Hualian Mansion Shenzhen Railway Station->Shenzhen Station

Ms Sophie,

Thanks for you prompt reply.

Hi Ms Sophie,

How about the actual location of Investment Building.

The Investment Building is located about 4kms to the west of the Hualian Dasha. Walking along the Shennan ZHong Lu to the west until to Shennan Da Dao, where the Investment Building is.
