For as long as I can remember, the countryside has been electrified. At that time, old-fashioned tungsten light bulbs were used, and the room was dimly lit by dim light. Tungsten filament bulbs emit light by heating, and the metal tungsten filament inside will emit dazzling light when heated to a certain extent. However, when the temperature is extremely high, some tungsten filaments will turn into vapor, which will cool and condense on the inner wall of the bulb. From the outside, it is the light bulb that is black.

The darker the bulb, the more the tungsten filament has evaporated. If the tungsten evaporates and the filament becomes thinner, the filament will break and the bulb will be unusable. So, the bulb turns black and the light dims, indicating that the life of this old bulb is almost over and it is time to replace it with a new one.

After a period of use, the light bulb would get dusty on its appearance, and Dad would often climb on a stool to wipe it. The bulb has been broken for a long time, and it is also a new bulb that my father replaced.

At night, I often see my sister doing her homework and memorizing texts in the dim light. When I don't have a playmate, when I'm bored, I move a high stool and sit with my sister doing my homework. Sometimes I deliberately blocked my sister's light with my chin propped up, casting a shadow, and then my sister would ask me to sit elsewhere. I rolled away and looked out the window at the round moon hanging high in the sky, and the stars in the sky. After sitting for a while, I couldn't get any longer, so I slipped out and found my own playmates.

The white moonlight shone everywhere, and the stars in the sky shimmered. When my friends and I were tired of playing, we would lie down on the grass and rest. Listen to the croaking of frogs in the distance and count the number of stars in the sky. And the older brother will call us stupid and tell us that there are countless stars. I didn't believe it, so I kept counting, and when I got to a certain number, I forgot the original number as soon as someone else interrupted. Moreover, at that time, my head couldn't hold too many things, and when I counted to a hundred, I didn't know how to count it later, so I just gave up. Pat the grass clippings on his body, said goodbye to his friends, and went home to take a bath.

The bulb is not always on, because the circuit is unstable, the main switch often trips and loses power, and sometimes even burns out and cannot be powered on. The house is dark, and at this time, the oil lamp that has not been used for a long time comes in handy. The oil lamp was made of iron sheets, surrounded by a ring of glass to block the wind, with a wick in the middle and a fuel cartridge under it for burning. The base of the oil lamp is very stable, it will not fall over easily on the table, and there is a wire handle on the top.

This oil lamp is extremely windproof and will not be easily blown out by the wind. When the power goes out, adults will carry oil lamps for lighting.

The disadvantage of this lamp is that the illumination area is small, and the oil will emit a choking smoke smell when burning. Curious about how the wick inside lit up, I often leaned in front of the lamp. After watching it for a long time, the smoke of the burning oil rose up, and the nose was hot. My sister said that both of my nostrils were blackened, and I immediately touched them with my hands, and my fingers were really black. I quickly washed it with water, and then I didn't dare to mess around in front of the lamp.

Later, oil lamps were gradually replaced by candles and tin flashlights. At that time, most candles were red, about thicker than an adult's thumb, twenty or thirty centimeters long, two cents a piece, and a little saved could be used for several days. When the candle is lit, the light of the flame takes on the shape of a dim yellow droplet. I heard that pinching the candle flame on it will not burn our hands, and our three sisters and brothers often play with the candle flame, which is more powerful than anyone else. Sometimes the candles were even extinguished, and my sister, who was sitting on the side doing her homework, had a blue face and a white face, and almost stood up and beat us little boys. Seeing that my sister's face was wrong, we immediately slipped out of the door. About half an hour later, I felt that my sister was angry, and while my sister was serious about her homework and didn't find out, the three of us sneaked home again. Sitting obediently in front of my parents and playing the role of a good child, my sister didn't dare to do anything to us at this time.

We also like to play with candle oil, when the grease of the candle burns and melts, there will be candle oil rolling down the body of the candle drop by drop. The candle drops that have just rolled off are hot, and after a while they have cooled and softened, we will accumulate the condensed candle droplets. If you save too much, you can roast it soft with fire, and you can play with plasticine and pinch out all kinds of good-looking small animals.

The tin flashlight is easy to carry when going out for a night walk, and it is almost a must-have for every family.

The flashlight has a bright silver exterior. A light bulb the size of a fingernail is placed in front of the barrel, and three to four No. 1 batteries can be used to illuminate it. In addition to the fixed switch, there is also a small red button that lights up when the flashlight is pressed. When the power went out, he took out the flashlight to play. At that time, I thought that the flashlight would glow and be fun and fun, so I turned the switch on and off, turned off and on, and the lights inside were bright and off, and the distance was bright and dark. And the village elders who were sitting not far away to enjoy the shade felt that their eyes were almost blinded. As he walked over, he said, "Which stinky boy is playing with a flashlight there, quickly turn it off for me." "I was afraid that I would find out that it was me, so I turned off the flashlight and ran away after a while.

When I was studying, I bought a mini black and white TV at home, about 17 inches. I remember that "The Condor Heroes" and "Huanzhu Gege" were very popular at that time, and our favorite is "Huanzhu Gege", I think the characters in it are vivid and smart, and the ancient dress and makeup are quite eye-catching. After reading the first part of "Huanzhu Gege", I will continue to watch the second part. It is the first palace fight drama in my life, and I always see it being rebroadcast on TV every winter and summer vacation.

At that time, the eldest sister worked and got paid, and she also bought a radio. At that time, there were two types of radios: single card and double card, and you could listen to songs by stuffing them into a cassette tape. There are about twenty songs on one tape, and the sound quality is not bad. After listening to the song on the first side of the tape, you can continue listening to the other side.

In the morning and evening, I can often hear my eldest sister singing, and the most listened to is the theme song in "Huanzhu Gege" and "The Condor Heroes". There are also pop songs from the 90s and 00s, such as those nostalgic songs sung by singers such as Teresa Teng, BEYOND, Zhou Huajian, and Ren Xianqi.

When I have nothing to do after school, I turn on the radio. Sit quietly in front of the radio and listen carefully to each song. Feel the stories in those songs, and carefully taste the touches brought to us by those songs.

Another function of the radio is that it can also be FM and receive cable TV broadcasts, one frequency band and one radio station. However, the disadvantage is that it is easy to be subject to electromagnetic interference, and once it is interfered with, there will be noise inside. At this time, we need to adjust the radio line, turn the FM button by the way, and change to the local station column, so that we can listen to a few beautiful songs.
