First, the first secret recipient is a person who mainly goes to four places. First, he went to the basketball court in the park and played for 20 minutes. Because the air circulation in the park is good, although he will have contact with other players when playing, but because he is not in a closed space, and the number of players is limited, the impact is not great, and he only played for 20 minutes, so there should be more than a dozen players in contact. After playing ball, he went to a nearby convenience store and stayed there for half an hour. I guess he bought something in it and ate it for a while. Because there are still many people coming and going in the convenience store and he stays for a long time, there should still be many influential people in this place.
Secondly, the first secret receiver went to Hu spicy soup shop for dinner. He ate in the shop for 8 minutes, but left at 8 am. At this time, the business in the store should be better, so this store should have many contacts. But fortunately, the time is not long and the impact is relatively small. At 8 o'clock in the evening, the secret receiver went to the streets to watch the square dance performance again. Because he was outdoors, he only stayed for 20 minutes. Even if he would come into contact with some people, the influence was limited because of ventilation.
Third, the remaining three secret recipients work together. They first went to the movie city and played in it for about five hours, which was still a long time. And it was Sunday, so there should be more people in the movie city. Although many amusement facilities are outdoors, they will definitely come into contact with many people, so the impact is relatively great. The hardest thing is people. These people are too mobile to be identified. After visiting the movie city, the three of them went to a nearby Huimian Noodles store for dinner and stayed there for about an hour. Because this shop is not big, the meal time is after 7 o'clock, so the contact with people should be limited.
