Dear Sir/Mam, I really do not understand at all about Hou-Lou. Would you kindly explain what exactly the Hou-Lou is. As I know that Hou-Lou is the Chinese Sacred Kabalash, is it true?But I still do not understand what it means and what the form is. Regarding Wou-Lou, should it have the cap so that the wou-lou is not opened? Because I bought the wou-lou with the mouth open (without the cap). And is there any certain conditions to hang the hou-lou and wou-lou? when the exact time to hang it up or to hang it down/take down)? I hope these questionsare allowed to be asked and I'm looking forward to have the answer/the explanation. Thank you. Regards, Srie
