Dear Cecil, Thank you for your comments. I like Ong Hean Tatt's scientific explanation about Shapes & Forms & why Yin sightings or radiations causing cancer (sha Qi) due to water underground etc.. In Singapore, ?Western Group? are advise to choose homes (refers condo) with North-South (facing-sitting), to avoid glaring afternoon sunlight. ?Western? Group when compared with Eastern Group will have less choices in buying a home according to their ba zhi, locations, favorable directions & flying stars. 1. Does the above conditions includes landed properties despite having awing, tress for shade & houses tilted sideways? 2. Is it true, houses which has NW facing & SE sitting built in Period 7 is not suitable to have water at their frontage( in their main door (NW) after Feb 2004?. Why?? Are they financial related? 3. What does it means when a house goes into a 20 years wealth lock in Period 8 (2004-2024)? E.g East/West (facing & sitting) houses built in Period 6 - financial wealth related?? I understand after every 20 years, the houses will lose their auspicious flying stars effects. Please elaborate?? Thank you. Regards Wincash.
