Nanjing as a child has changed a lot compared with now. At that time, I lived near the Confucius Temple. At that time, there were not so many people. I basically went out on foot, with few buses and few bicycles. At that time, Jiankang Road was also called Jiankang Road. I remember that there were arrows on the sidewalks on both sides of the road. Pedestrians walked on the left and right sides with a red dividing line in the middle. According to the old man, it was built by the people to carry out the new culture movement and improve the quality of the citizens. In the 1970s, the north of Nanjing was still very deserted. I remember once taking the No.31 cable tram to Shimonoseki. It was only seven or eight o&;clock in the evening, and both sides of the road were dark and almost no lights could be seen. It won&;t light up until after the Drum Tower. What impressed me more was watching movies. It&;s hard to get tickets for a good new movie. At that time, the movie ticket was only about 10 cents. There will be a lot of refunds waiting at the gate of the cinema. Nanjing people call it a pocket ticket. Of course, there will be many scalpers raising their prices, and if they really want to see it, they will buy high-priced tickets. In the era of lack of materials, basic daily necessities need to be bought by ticket vouchers. Eating meat is also a luxury. Some people go to the buns shop to buy meat buns, eat the skin, and treat the meat inside as meatballs, which is really a way to find a way. So you don&;t need a meat ticket to eat meat. Now every family has running water, and it was a happy thing to have running water in the 1970s. Especially in some old houses, it is necessary to carry water for draught and water use, and pour it into a large vat, mainly for eating, and then drill well water for washing. Not only is there little tap water, but there is no gas. Coal stoves are used to burn coal, and every household will find empty places to pile up in corridors and corners. Now Nanjing is very urban. Many years ago, only the south of the city and the city were prosperous, and the development of other places was obviously backward. Today&;s Nanjing rich area ~ Hexi, many years ago, was still a lot of farmland, most of them lived in shacks, and the streets were still dirt roads, and they were very narrow. There used to be a bus No.7 from the city center. It was really sunny and dusty, and it was muddy in rainy days. It is conceivable what the road conditions were like at that time. This is just a fragmentary impression of Nanjing when I was a child, and it is also a kind of memory.
