Bars originally originated from western pubs during the development of the western United States. The word bar didn't have the meaning of "selling drinks over the counter" until16th century, and then it evolved into a comprehensive consumer place providing entertainment and performance services with the development of the times, and was introduced to China in 1990s. Nightclubs are different from bars. The NightClub is night Club, often referred to as club, and the Bar is bar.
People in China often mistake nightclubs for bars. Let's literally explain the difference between nightclubs and bars. Generally, shop signs at the door should indicate whether they are clubs or bars. CLUB is a nightclub (full name: nightclub) and BAR is a bar. In fact, the two are different. So bars are just bars or pubs, while clubs are actually nightclubs, not bars.
