Bar is a synonym for pub, and its English name is Bar. It originated in the western development period of the United States.
Bars originated in continental Europe, but it wasn't until the 6th century AD/KLOC that the word "bar selling drinks" came into being, and then it was further mutated and expanded in the United States, and it only entered China about ten years ago. The word "ba" is still a recent thing.
After entering China, bars have developed rapidly, especially in Beijing, Shanghai and Guangzhou: bars in Beijing are rough and open, bars in Shanghai are delicate and sad, bars in Guangzhou are lively and complicated, and bars in Shenzhen are the most passionate.
The night sky in the city can't be separated from the bar, and urbanites can't be separated from the bar. People need to forget and indulge in busyness.
