I will be taking a bullet train from Suzhou to Hangzhou.

Although Chengzhan Train Station (Main Station) is nearer; there is only one bullet train from Suzhou there. You are suggested to go to East Station, which is about 12km away. And then take metro line 1 to Longyangqiao and leave from Exit D2. Walk east for 2 minutes to Longxiangqiao Bus Stop to take bus 4, and get off at Jingsi Temple.
