This evening the health condition of my mother suddenly became worse. She complained of shiver. Maybe the shiver she had was very strong and she got really upset. Of course this is also my first experience, so I asked my sister for assistance. When my mother looked at my sister, she seemed to be relieved. My mother, sister and I talked for about two hours to see her condition. Right now, she is sleeping well. When I talk to my mother, I really have to use soft words not to let her feel nervous.
