(1) Clothing: People's clothing basically reflects the economic outlook and modernization of a country or region. Before the Revolution of 1911, many people with lofty ideals took the lead in cutting off the braid symbolizing the Qing Dynasty and expressed their determination to oppose feudal autocracy. After the Revolution of 1911, the Nanjing Provisional Government issued a braid cutting order. In a few years, most men in the country cut their braids. The change of clothing is the appearance of tunic suit and cheongsam; At the same time, the bad habit of foot binding, which was harmful to women's physical and mental health, was abolished. For a long time before the reform and opening up in New China, people wore the same gray Chinese tunic suit or blue liberation suit, which was described as "blue (gray) ocean". At that time, people had to buy clothes with cloth tickets. After the reform and opening up, with the development of economy, clothing styles gradually diversified. Mainly men's suits and jackets, women's styles are more. Jeans are the favorite style of boys and girls, and they are also the most popular. Fashion shows showing novel styles will continue one venue after another, and the ever-changing fashions are dizzying. (2) Diet: Eating habits have strong national heritability, and are also greatly influenced and restricted by the natural environment and production methods. For example, the staple food in rice-growing agricultural areas in the south is rice, while the staple food in dry farming areas in the north is oats and millet. During the Republic of China, there were new changes in the diet structure. In some coastal cities, western food has gradually become a fashionable food. Cigarettes from abroad crowded out tobacco and hookah in China to a great extent. These phenomena have changed the traditional food industry in China. But in the vast rural areas, poor farmers still eat chaff and swallow vegetables, and there is no market for western food at all. From the late 1950s to the 1960s, the state rationed food for urban residents. With the development of economy, especially since the reform and opening up, the diet structure of most people is changing. Mainly due to the diversification of diet, the proportion of staple food has gradually decreased, and the proportion of non-staple food and fruit has gradually increased. The content of staple food is also changing. Rice, flour and other flour are staple foods, and the number of people who eat corn flour and sorghum flour is gradually decreasing. Meat food, all kinds of fresh aquatic products, fresh vegetables and drinks can be bought everywhere. (3) Housing: In terms of housing construction, there were still a large number of old-fashioned houses in cities and thatched houses in rural areas during the Republic of China. In coastal cities, some wealthy businessmen and bureaucrats built "foreign houses". There are electric lights and running water in the houses in the city, which brings convenience to the lives of ordinary people. Since the founding of New China, especially since 1980s, residents' housing has been continuously improved. Not only has the per capita living area expanded, but the interior decoration and living environment have also improved significantly. (4) OK: Traffic improved to some extent during the Republic of China. Sedan chairs and carriages are gradually decreasing, and rickshaws and bicycles have become common means of transportation. There are asphalt roads, buses and trams in the city. Road and railway traffic has also developed. After the founding of New China, great changes have taken place in traffic. Many new railways have been built. Besides buses and trams, there are taxis in urban transportation. Some big cities have begun to own subways. Bicycle is the main personal means of transportation for urban and rural people, so China is called "Bicycle Kingdom". Civil aviation has developed rapidly since the reform and opening up, and now all the people can fly. Making use of holiday tourism is a great change in the life content of many people in China since 1980s. People gradually broke the closed living environment in the past, leaving their families, their hometowns and counties, and traveling abroad.
