Master Cecil Lee, Thank you from you prompt reply. Basically, the house is under construction which I presumed the traffic is moderate after completion. My answers to your questions: 1 & 2) Yes. The vechicles come to me at the main gate. No garden nor tree. 3) The distance is around 15 meters from the main gate to the L shaped road. The front house protected by wall and iron gate. 5) I'm from Malaysia. Its RHD. May I ask if the front road of the house able to work as a barrier to isolate this bad chi?
