Our guide just wants to deal with it in a targeted way, because the students in my family are concentrated and scattered in various counties of a city. Secondly, they are close to the tour guide's home, so the tour guide chose this position. The selected home visitors are the class committees familiar to the tour guides and students who do have some problems, but they are all within this area. I belong to the former. I actively help guides at school, with high grades and good personality. So it is purely to help the wizard complete the task. As for dialogue, the following is a brief introduction, which is a problem encountered by normal college students. Finally, I want to say that our guide is really good and our relationship is good, so this home visit is still very smooth.
