约12:05我来到这在此时小学生还在大量聚集和行走，左侧队和右侧主窗口队列几乎无人，右侧面条吧队列大概达到了第一课绿植左右的位置。随后的几分钟内这些队列的移动非常缓慢。整体来说面条队列的移动大概在1分钟3-4个身位。在一小段时间后，一批学生前来瞬间将面条队列延伸到第二颗绿植旁，随后缓慢增长到卫生间旁。主窗口左侧队列增长较为平均，但也有明显的先快后慢趋势。右侧披萨队列和面条差不多，但有两次激增，整体时间偏后。我未观察到披萨吧后侧队列，仅在约12:17离开时观察了一次。学生到达成批次，在这段时间里有若干次学生数量激增。并未观察到明显的退出队列或换队。排队时学生几乎站在原地不移动，队列整体较松弛，学生与学生的间距较为宽松。大约80%的学生都来自于面条吧同侧的走廊，那里有三个入口：室外，楼道和与其垂直的一条走廊。二楼拥挤分布分厂均匀，天井周围几乎没有学生。
12:15
准备离开食堂，观察到面条队列的处理速度极慢，披萨吧的队列到走廊侧戛然而止。
12:18
离开了食堂，同时观察到了三明治吧的队列从吧台中间向初中教学楼侧沿墙壁延伸至走廊。一楼与二楼食堂座位还有明显空余。但考虑到学生大多成群结队入座并由于社交因素，整体还是偏向拥挤。
12:30
三明治吧座位几乎坐满，比之前还拥挤，一楼座位还有明显空余，且空余位置增加。所有窗口几乎无人。可能原因是相当一部分人在一楼取餐后前往二楼就餐。

At around 12:05, I arrived at this location. At this time, elementary school students were still gathering and walking in large numbers. The left-side queue and the main window queue on the right were almost empty, while the noodle bar queue on the right had reached the area near the first green plant. Over the next few minutes, the movement of these queues was extremely slow. On average, the noodle queue moved at a rate of approximately 3-4 people per minute. After a short period, a group of students arrived and quickly extended the noodle queue to the second greenery area, then slowly grew to the restroom area. The left-side queue at the main window grew relatively evenly, but there was a noticeable trend of starting fast and slowing down. The right-side pizza queue was similar to the noodle queue, but there were two spikes, and the overall timing was later. I did not observe the queue behind the pizza bar, only once at around 12:17 when I left. Students arrived in batches, with several spikes in student numbers during this period. No obvious exits from the queue or switching queues were observed. Students remained almost stationary while queuing, with the queue overall being loose and students spaced fairly widely apart. Approximately 80% of the students came from the corridor on the same side as the noodle bar, which had three entrances: outdoor, hallway, and a corridor perpendicular to it. The second floor was evenly crowded, with almost no students around the atrium.
12:15
Preparing to leave the cafeteria, I observed that the noodle queue was moving extremely slowly, and the pizza bar queue abruptly stopped at the corridor side.
12:18
Left the cafeteria and observed that the sandwich bar queue extended from the center of the counter along the wall toward the middle school building side of the corridor. There were still noticeable empty seats on the first and second floors of the cafeteria. However, considering that students mostly sat in groups and due to social factors, the overall environment remained relatively crowded.
12:30
The sandwich bar seats were almost full, even more crowded than before, while the first-floor seats still had noticeable empty spaces, with the number of empty seats increasing. All windows were nearly empty. The possible reason is that a significant portion of people took their meals on the first floor and then went to the second floor to eat.
