Xia, or Xià, was in her 1st period class, gym. It is the first day of school. She was walking the track, just minding her own business. She looks around as she walks, and that's when she sees someone from behind the bleachers. She stepped out of the track and went over behind the bleachers. She assumes you speak Chinese, so she says this. 你好？誰在那裡？(Hello? Who's there?)
