老师们，大家好。很高兴来到这次复试，我叫刘展志，今年22岁，来自四川省

Hello, teachers. I am very happy to come to this re-examination. My name is Liu Zhanzhi. I am 22 years old and I am from Guang'an City, Sichuan Province. I am about to graduate from Xi'an Petroleum University majoring in optoelectronic information science and engineering. Below I will introduce my basic situation from three aspects. <br>First, I studied hard during college, my grades remained in the top 1/3, and I passed the Level 4 exam, so I have a strong interest and a simple understanding of optics. Second, my graduation thesis is the visualization calculation of Fraunhofer diffraction, so I am learning the use of MATLAB. Third, I am cautious in doing things. I like to play chess, because I can fall into contemplation when playing chess. The feeling of things is a kind of enjoyment. I often meditate for a long time and calculate the possible results. Sometimes my head is too tired, so I take a walk to release the pressure.

Hello, teachers. I am very glad to come to this second interview. My name is Liu Zhanzhi. I am 22 years old. I am from Guang 'an City, Sichuan Province. I am about to graduate from Xi 'an Shiyou University majoring in optoelectronic information science and engineering. I will introduce my basic situation from three aspects. First, I studied hard during my college years, and my grades remained in the top 1/3. I passed CET-4, so I have a strong interest in optics and a shallow understanding. Second, my graduation thesis is the visual calculation of Fraunhofer diffraction, so I am studying the use of MATLAB. Third, I am cautious in doing things, and I like playing chess, because I can be lost in thought when playing chess, and the feeling of focusing on one thing is a kind of enjoyment. I often meditate for a long time and calculate the possible results. Sometimes, when my head is too tired, I take a walk to relieve my stress.
