Where is the square in Suzhou? What is the fastest bus I can take from Park Lake East?

It's in the southwest of Suzhou, so it's not convenient to take a bus.

Hudong Neighborhood Center takes bus No.2 (23 stops) to Leqiao (Leqiao Station of Rail Transit), bus No.305 (13 stops) to Youxinlijiao Bridge, and bus No.415 (4 stops) to Shangfangshan National Forest Park.

Or take the 1 express (7 stops) on Xizhou Road, 200 meters west to Shishan Street, take the No.2 customs declaration line (2 stops)/No.37 customs declaration line (4 stops) to Hengtang, and take No.415 road (5 stops) to Shangfangshan National Forest Park.
