kk sir, I'll be flying that day ah. I suspect this would not be an acceptable reason for you to ask your other half elect to consider a change of dinner schedule wor.
I got the information from our Lab Tech. After the renovation of the lab, he sits next to the 電箱 in his lab and after one or two weeks he got terrible headache. He thinks that it is the Electro-magnetic wave from the HUGE power supply box that is affecting him. So he coats a layer of Lead Plate on the inside of the door.
The plate are around 3mm thick and around 16 - 20" wide. As it is Lead, you can cut it into different size. The lab tech told me that he got these plates from stores selling metal goods along the street you are living. BUT he isn't sure whether these shops are still there as he got them more than 1 year ago. :cry:
Just wonder whether those shops are still there. If I have more free time this week, I will take some photos of those LEAD plates. It will be easier for you to find then.
Dear Alfcat,
I checked it for you today, some shop keeper said it hard to find the lead product in this district now. You can check one shop called Heng yick at Prince Edward Road.
