The process of writing this paper and developing the system is also a process in which I become more and more aware of my lack of knowledge and experience. Although I try my best to collect information and use what I have learned to write a paper and develop a system, there are still many shortcomings in the paper and the system is not fully functional, which needs to be improved. Please criticize and correct me, so that I can learn more in my future study.

When the book is used, I hate it less. It's not difficult. Let's talk about it later. Under the guidance of my teacher, I know how to write my graduation thesis. Through this graduation thesis writing, I feel more and more lack of knowledge and narrow vision. There is a long way to go in Xiu Yuan, and I will go up and down. My humble job, please be honest with the teacher.

In the process of making this design, I collected as much information as possible, learned a lot of useful things and accumulated a lot of experience, but because of my shallow knowledge and lack of cognitive ability, there are many biased and shallow places in understanding; Because of the weak theoretical foundation, there are many problems of poor logic and unsatisfactory wording; In addition, the time is short, and I am careless, which is far from the teacher's expectation. Many problems need further thinking and exploration. I sincerely hope that all teachers can put forward valuable opinions and point out the mistakes and shortcomings of this article. I will accept it with an open mind in order to further study and improve the design. My introduction is over, thank you! Ask the teacher to ask questions.
