Hello Mr. Lee: My house was built new and completed in December 2002. We moved in the same month. The House faces NE - 64 Degrees. My Kua Number is 2. I believe it is advantageous to move from Period 7 to Period 8. To accomplish this, we have to perform a 'major' renovation. Will replacing the entire Front Door be considered as a major renovation? We cannot renovate in other (possible) portions of the house since they fall in West and NW sectors, which are the areas of the Grand Duke. In Period 7, the Front Door portion occupies Flying Star-1, Water Star-7 and Mountain Star-7. In Period 8, The Front Door portion occupies Flying Star-2, Water Star-5 and Mountain Star-8. Do you recommend replacing the Front Door? In your opinion, is it better for us to stay in Period 7 or move to Period 8? If you have any other suggestions, please let us know. With Respects and Regards, Rathan.
