how to go pearl river if i from jinan hua wen gongyuan road ?? please tell me how to go

Hi, do you mean Jinan University Huawen Campus? If so, it is located at Shougouling Road.
From the campus, you can walk along Shougouling Road to the local East Railway Station to catch subway line 1 to Gongyuanqian MTR Station, where you can transfer to subway line 2 to Haizhu Aquare Station. Get out from Exit A and you can see the river.
