In both sets of grandparents houses, it was considered SAN BA or country. Until 1970s, they did not have electricity supply. In the bedrooms, we used a tiny kerosene lamp.
There was one pressure lamp in the lounge. We kids were interested when the pressure lamp was lighted. 7th Uncle Peter Yin Fei was responsible for getting the lamp down the beam while standing on a chair. With the lamp on the floor, he authorized us not to crowd too near him as he goes on his important job. First, he pours kerosene into the base. Then he pumps, if we were good, he would let us have a go. Finally he lights the bulb. The whole room glows like it was lit by a florescent light. The bulb or the mantle is made of some sort of fibre of asbestos. One day, my curiosity killed the cat. I touched the mantle and simply melted away. 7th Uncle asked who touched the mantle and nobody admitted. Peter thought the bulb was faulty.
