Nowadays, with the expansion of University enrollment, the number of college students is soaring, and the school canteen space is limited, so it will be particularly crowded when it comes to meals. Most students usually have the same time after class, so around 12 o'clock there will be a large number of people rushing to the canteen. Then there will be a long queue in the canteen waiting for the order. Line up on time, and because the teacher delayed a little late to the hall, can not find anything delicious. If there is such a dining hall order (exchange) platform, which can ease the flow of people and make it more convenient for teachers and students to order meals quickly, it will greatly save people wandering in front of the window to check the dishes, waiting time for meals and prevent them from losing delicacy.


Because the canteen is crowded, many students want to avoid the trouble of waiting in line and finding seats during the rush hour. They simply call for takeout or go to Heichao to buy pancakes and hot and spicy dishes. Some students simply eat good instant noodles. However, whether it is takeout or hot pancakes, these things will not have food safety protection, and school canteens supervised by relevant departments can ensure the balance of nutrition and food hygiene. In order for lazy students to eat healthy and convenient food, we must solve two problems: waiting in line and not ordering in advance.


With the rapid development of science and technology, mobile phones have become people's inseparable "partners", and online ordering is becoming more and more common, many businesses are involved in it. So my suggestion is to develop a micro-messaging platform that can order meals online for teachers and students to choose dishes. This not only alleviates the pressure of the flow of people in the peak period but also provides a convenient channel for teachers and students. At the same time, this platform can also extend a communication path between teachers and students and chefs (because not many people will write to complain about some bad things after eating). If this communication path is established, it will greatly shorten the distance between chefs and diners, and we can communicate "zero distance".


In order to verify the feasibility of this scheme, our group designed the following experiments. We recruited 200 volunteers and divided them into two groups, A and B (100 in each group, men, and women are not limited) (participants). Group A ordered meals on the dining platform on Monday before lunch in the second teaching week. Group B ordered meals on the third floor of the school canteen at 12 noon on Monday in the fourth teaching week. Group A ordered meals on Wechat platform and could choose to eat or take them away. Group B ordered meals in line and could choose to eat or take them away in the canteen (independent variable). Observe and take photos to record the satisfaction (dependent variable) of the two groups of volunteers. Obviously, the satisfaction of group A volunteers who ordered meals on our Wechat platform was much higher than that of group B volunteers who ordered meals off-line. This shows that our Wechat ordering platform can indeed help us order meals in advance and save queuing time (results and discussions).
