May I know how to travel from Hotel Equatorial to Zhujiajiao? If is by Taxi how much?

You can take bus Hu Zhu Special Line at Middle Yan'an Road Huashan Road Station, get to ZJJ Bus Station first. Then walk northwest to arrive at the water town directly.
If you wanna take a cab from the hotel, the fare is CNY 150-180 in usual time. Besides, as I know, there are still some cabs in late afternoon. If not, there are also many private cars. Just pick one and return back to downtown area.
