Xitang one day visit

I am confused about transportation to Xitang from Shanghai. Is there a tour bus running daily with a guide that goes there from Shanghai stadium . I read somewhere that it only operates on the weekend. I would also like to know if the bus takes you directly to the water town. I also read somewhere that you have to walk for about 20 minutes after getting off the bus. Is this true? One final question, which is easier for a non Chinese speaker, to take the train or bus to this water town? Thank you so much for your help.
