In the early days, people were very poor and only lived in thatched huts and adobe houses. The conditions were extremely difficult at that time, but our fathers survived.
Later, conditions improved, and people gradually lived in large tile-roofed houses and brick houses (some were also small pigeon nests), but life was still very inconvenient because the toilets were shared and bathing was difficult. You have to go to the public bathhouse, but the only reason why people are happy is that they live in a big yard, just like a big family. Although there are few childhood games, people are not short of happiness.
Later, there were large-scale demolitions, and most of the bungalows were replaced by more high-rise buildings. People gained the long-lost private space and the long-awaited comfort and tranquility, but at the same time they also lost The warmth, solidarity and friendship between neighbors make people become more and more indifferent.
