Here’s a picture of Wu lou that I use to counter the sickness star #2 in the Flying Star Feng Shui. As a matter of fact, I have several wu lous in my house… I put one in the North-East sector (home of star #2 in the current Period 8 – from February 2004 to February 2024) of our house; another one in the North-West sector for 2008 where annual star #2 resides, and which I will move to the West sector where the star #2 will be located next February; I have a third one which I move monthly to the different sector according to the Monthly Flying Star, for example it is in the South-East sector for this month. Finally, I also place one each on our children’s and our night tables to ensure good health.
This is no superstition and can be explained by Yi Jing (The Book of Changes). Master Joseph Yu has written an article on this, just click on the following link if you’re interested:
