Public bathrooms, commonly known as big bathhouses, are mainly distributed around residential areas north of Huaihe River in Qinling Mountains and inside universities. It is a magical invention that combines the blood of northerners and is regarded as a scourge by southerners. Generally speaking, the farther north the city where the university is located, the more unrestrained the form of public toilets, such as Liaoning University and Dalian University of Technology, which have no compartments and shower curtains; In Southern University, each dormitory is often equipped with a separate bathroom with a shower head for four people. Some central cities have neutralized these two toilet modes, and set up small public toilets on each floor or building. So geographically, the bathroom is still very different.
In the north, the influence of bathing in winter on water temperature and room temperature has contributed to the rise of public toilets. Bathroom owners use large boilers to boil hot water and lay pipes and radiators, which provides bathing conditions that ordinary people can't create. Before the market economy, large bathhouses were basically state-owned and the ticket prices were not high. The number of state-owned bathrooms in a small city is not too large, and it is crowded every day in winter. Limited by material and economic conditions, it is impossible to install radiators in every single room, so I opened it and laid a group of large radiators to heat the whole bathhouse. Northerners, frozen to the wall, had no choice but to forget the word privacy, so the big bathhouse without compartments was handed down.
Therefore, it is understandable that girls in the south are afraid of the differences between the north and the south caused by geographical reasons. After all, most girls in the south are introverted and shy, and they may be scared to cry when they see such a bold and unrestrained bathhouse.
