There are many strange phenomena in China, most of which are short-term phenomena in social development. These short-term phenomena will affect people's lives in China at one time, but they will gradually disappear in the long run. For China, these things are some troubles caused by a certain stage of economic development, which will not last long. The state will settle people's lives again through a series of policies.

Now there is a phenomenon that more and more people are working and getting married in a city. Twin cities are a term born in this way. In fact, Twin cities are the temporary phenomenon I mentioned above. Because the development of cities has just entered a stage, the solutions to some cities with foreign population need to be improved, such as Beijing, Shanghai, Guangzhou and other big cities, but these problems will be solved step by step.

Most of the Shuangcheng people are young people. They have just started working for a few years, so it is not a realistic thing to buy a house in the city where they work. It takes two people to make more efforts, and this problem will be solved after working for at least ten years. Another phenomenon of the Shuangcheng people is that they have a house in the city where they live, but they don't have a house in the city where they work. They are not willing to sell their current house and buy a house in the city where they work. This phenomenon is many now.

There is a big gap in housing prices among cities in China. For example, in Beijing and Shijiazhuang, the difference in housing prices between the two cities will be more than one million, so people called Shuangcheng people have no way to adapt, and of course they can't afford to buy a house in Beijing. This phenomenon is everywhere in China, and the comparison of this social phenomenon is that more and more people are separated from each other, and high housing prices are another reason for the formation of the twin cities.

Because of these reasons, the number of people with twin cities has gradually increased, and the twin cities have become a phenomenon in China. The rapid increase of population in cities, high housing prices and unstable mobility of people are all phenomena that cause the twin cities. However, this is not a sad reminder of the times, but a driving force of the times, because the country has begun to focus on solving positive and negative social phenomena. I believe this will gradually get better in the next few years.
