Any information on Xi Shui Y Mn S Cun and Jin Tang Shan Zhuang in Beijing?

I know Xishuiyu is located in Huairou District of Beijing, which could be reached by bus from Beijing. If you have a group of students, you'd better hire a van driving there, not close from downtwon Beijing. However, I think these teenagers may be more interested in Happy Valley rather than a quiet local village for leisure at weekend/
