Walking on the campus of Peking University, how can you tell at a glance whether a boy is from Peking University? Liu's method is to look at the height first.

He uses himself as a benchmark ruler, and those who are below his height can basically brush it directly. Because according to statistics and his careful verification, there are almost no boys below his height at Peking University, which means that his height accounts for very few and very few, and most of them are higher than his height.

The second step is to look at the equipment, the standard equipment of Peking University boys is to carry a large backpack, and there is a drinking cup inserted in the mesh bag on the side of the backpack.

Is there a use for these? Based on these two items, Liu Zhilu deduced the probability of success of a boy from a foreign school to Peking University.

If the boy who comes to Peking University to take the postgraduate entrance examination is shorter than Liu Zhilu, and he usually goes to Peking University for self-study and is not that set of equipment, then he will conclude that this person is eighty or ninety percent useless, and the exam is in vain; If he is taller than him, and he is usually the standard equipment of Peking University boys, then he will infer that this person can be admitted six or seven times, and if he doesn't get admitted once, he can take the test a few more times. His set really has a chance to be tested.

During the second Mid-Autumn Festival when he came to work in the bookstore, Liu Zhilu spent it with a group of people who came to Peking University to take the postgraduate entrance examination on the island in the middle of Weiming Lake.

On this day, they sent someone to occupy a stone table on the island in the middle of the lake in advance. When the time came, some people came with fruit snacks, some people carried moon cakes and snacks, and some people came with beer and drinks.

Most of these people are research friends of Liu Zhilu's roommate, and Liu Zhilu was called mainly to accompany the guitar and play and sing to help the fun.

Liu Zhilu carefully observed this group of people and found that there were only two boys who were taller than him. Among them, one is about to study for a master's degree and a doctorate at the School of Mathematical Sciences of Peking University. According to his method, only one of these boys can be admitted, and he thinks it's quite miserable. Afterwards, it was really as he deduced, that is, only one person was admitted, but he was deployed.

There were only three girls who came to this night's party, and they also came to Peking University to take the postgraduate entrance examination, and in the end, they did not succeed in the examination. In the middle of the term, Li Miaomiao, a girl from Inner Mongolia, impressed Liu Zhilu the most. Because her height and figure are similar to Yang Nannan's, but her face, skin, and learning ability are inferior to Yang Nannan.

It can be joked that Li Miaomiao is the Chinese version of Yang Nannan, but it is definitely unique. Liu Zhilu could only get such a version at that time.

Fortunately, this night, Liu Zhilu just went to the playground with Li Miaomiao to go to the toilet, and returned to the island in the middle of the lake along the road. If they had walked along the Weiming Lake, there might have been a story!
