This is another easy task, just find and clean. Not difficult I promise.
As much as the transparent roofing is good to get the lights in along the pathway, it also has a horrible side to it.
Look at the filth and rubbish trapped on the roofing. Not only you have those, you can also find cloth clips, tissue paper, clothes, chewing gum wrappers, cigarette butts and the list continues. When ii rains, all these will be on the floor.
Can GE Tan instruct the cleaners to remove those rubbish from the transparent roof? It is a bad fung shui, you know, to have rubbish above your head.
