When I was about to rent my HK crib I noted electricity cords coming out of the wall and made a comment to the agent showing me around; excuse me Mr but what about those 220 volt naked electricity vires? He looked at me with tired eyes and replies me back; just stay away Miss and you will be fine! My brother looked at me with worried eyes but I was convinced; oki I’ll take it! I also learned to place a magnet on the electricity box hanging outside the front door to increase the bill. Handy. Now I am subletting the place with the same good words ‘just stay away and you will be fine’.
