Ms. Chen didn't know what time she fell asleep or what time she woke up. She stretched in front of the computer desk and realized that she had slept for a long time. As usual. At eleven o'clock, she packed her things for work tomorrow and put them into the black handbag that she had carried for almost a year. It was already a bit old, but Miss Chen liked it very much. She fetched a basin of water and put it in the room. After brushing her teeth and washing her face, she used it to soak her feet. This was a habit that Ms. Chen developed after she was 20 years old. It is said that foot soaking can beautify the face, soothe the mind and help sleep, but Ms. Chen has never thought of it that way. She just wanted her feet to be warm when she slept, in this single rented room of only fifty-six square meters.
