If people didn't take a bath for a long time because of inconvenient heating in winter, they needed to take a bath in the big bathhouse outside, in fact, this situation basically no longer exists. Many rural areas have started central heating, and the temperature at home is enough to take a bath in winter, but everyone is used to finding someone to take a bath, so they are willing to go outside, just like cooking at home often and eating in restaurants outside occasionally.
Bathing is not because it is dirty. Bathroom (bath center) can provide sauna and medicine bath service. Northeasters spend more time in winter, unlike the south, which needs to work in four seasons, so they have a lot of leisure time. Some people will go out to work, and most people will stay at home, so this is also a manifestation of enjoying life and is good for health maintenance. Bathing can promote blood circulation, while sauna can make people sweat passively and excrete toxins from the body through sweat.
Saving water resources is also a reason. We know that the water in a good bathhouse is recycled, which saves water resources than bathing at home. Whether you use electric water heaters or solar water heaters at home, you will be limited by the container capacity, so there is a time limit. It is also problematic to occupy the bathroom for a long time at home. Is there any professional service? So people who pursue enjoyment like to take a bath in the bathhouse. This is especially true for people who have annual ticket membership cards. It's money if they don't go anyway. They can also use the money to treat people and take it to their relatives and friends. Compared with going to restaurants to drink and eat meat (everyone is overnourished), it is a relatively healthy project to invite people to take a bath.
Living habits are cultivated for a long time. Although each place has its own characteristics, the development of transportation and the popularity of the Internet have accelerated the process of cultural exchange. In fact, many people in the south have begun to like to take a bath, and there are more exquisite places in the north. As long as living habits are beneficial to our health, they will be gradually accepted by everyone.
Just like old Beijingers like to take a bath, it is actually a unique culture, mainly because of the slow pace of life in the past. There is not much difference between inviting people to take a bath and inviting southerners to a teahouse for tea and chatting. Only best friends can go together.
