According to legend, Wu Zetian, the only female emperor in the history of China, likes bathing very much and often spends half a day in hot springs. And Wu Zetian is particularly particular about bathing. According to the different weather, she will mix all kinds of petals, scatter them in hot springs and enjoy the petal bath.
In Luoyang, there is a saying that Wu Zetian loves to take a bath, but she doesn't like to take a bath in a wooden basin. She had to take a pool of hot springs as her bathing place, which means that Wu Zetian's bathing place is amazing. In fact, most people say that Wu Zetian Bathroom is a site unearthed in 1986.
