An international student from China washed his feet in a public toilet in the United States, and his roommate reported to the school that it was unsanitary. I lived with a German man for half a month. He doesn't even have a footbath. He wipes his feet with a towel every day. After a long time, his feet were covered with sticky mud. In modern European and American TV dramas or reality shows, men's and women's socks are so dirty. I wonder if they just take a shower and don't wash their feet, so they wash their socks when they are dirty. Unlike people in China who wash their feet and socks. However, in the American drama Roman Empire, the hero's wife washed his feet, and in the German film The Queen, the men of Emperor Frank lothaire also washed his feet. The Victorian English drama Que Qi Xiang went to Candle Town to wash his feet. James McAvoy also washed his feet in the World War I movie Redemption. Li, a World War II movie in Czechoslovakia, Bulgaria, also washed his feet. But modern Europeans and Americans wash their feet. Only in the French film Sambali did I see a black man and an Arab washing their feet. I asked a Brazilian student, and he said that some people just take a bath before going to bed. But the problem is, if you only take a bath, your feet can't be washed clean. You can't sleep without washing your feet before going to bed.
