We bought a new house. The main door is facing NW. Heard the 'wu-huang-sha' (5-yellow-sha) is on NW this year 2005 so it is not good to renovate. Is that ok if we start the renovation now but only move in next year (2006) after Lunar New Year? Besides, in front of the main door, if I stand facing outside, on my right top about 100m, I can see thesharp corner roof of my neighbour house. Is changing the main door direction the only way, or any other ways to exhaust the 'cha qi'? Thanks a lot! My gua is 7 and my husband is 9.
