润色如下内容：To study artificial intelligence and big data at university has been my dream from a young age. Some of my earliest memories are of sitting with my father in the study watching him study electronic devices and telling me something about computers, which has helped me gain a basic understanding of computer usage from an early age and sparked my curiosity and interest in computers.Later, I joined a robot programming class in middle school and initially learned programming and application, laying a foundation for my computer learning. Most importantly,computer science and machine learning have bright prospects and talents with related background are popular in terms of employment, therefore I would like to apply for artificial intelligence and big data at postgraduate level.

During my university years, I studied a variety of courses such as C language, C++, Python, Linux, Database Principles, Computer Networks, Computer Composition Principles, Operating Systems, Data Structures and Algorithms, Information System Security, Network Security Technologies and so on. Through studying these courses, I have mastered the basic composition and principles of computers, acquired basic programming skills, and the ability to learn other programming languages  independently. I have a certain understanding of computer networks and information security technology. What’s more,I have demonstrated good self-learning and teamwork skills in my learning and daily life as I am able to self-learn new programming languages and collaborate with classmates to complete classroom projects. 

Except what should be learned at university,I tend to develop my knowledge and skills in terms of computer in my spare time.The experience of learning PHP and HTML, CSS and JavaScript has equipped me with basic knowledge of web programming and improved my self-learning ability. I also have participated in extracurricular lectures organized by the university where I learned about the importance and practical application scenarios of network security in modern times, and gained exposure to cutting-edge knowledge in the field of technology.

Outside of the academic setting, I have had internship experience and the most meaningful one was in Shenzhen Qichuang Oriental Technology Co., Ltd. during a summer holiday. Through this internship, I have gained a deeper understanding of the use and operation of computer networks, and learned how to write application programs and front and back ends of web pages. I believe that these experiences have a positive impact on further research on computers. During the internship, I needed to work with colleagues on projects according to requirements, which helped me better understand what needed to be achieved in practical work and related technologies. This gave me some project experience and a clearer understanding of the direction and needs of future career choices. During the communications with colleagues, I received many insightful suggestions, understood some basic rules, and learned how to communicate with others in the workplace, which laid the foundation for my future employment.

As for my career planning,I hope to work in software development or network security after graduation. I would like to work in a state-owned enterprise, or first experience in small and medium-sized companies, and then use this as a foundation to enter large companies. Meanwhile,I will continue to learn new skills and technologies, maintain a focus on the latest industry development, participate more in projects and accumulate rich project experience. Apart from work, I am willing to obtain relevant certifications such as software engineer certification, to demonstrate one's professional level and participate in industry related conferences and training to improve professional competence.After accumulating some experience, I plan to try different fields such as mobile development, cloud computing, artificial intelligence, etc.

I am heartedly grateful for what I have been able to learn through my undergraduate years, but I do not believe that should be the end of my education journey. Knowing that Master of Science in Artificial Intelligence and Big Data Computing at the Hong Kong Polytechnic University provides both basic and advanced courses on computer industries. I sincerely hope to be allowed to study at Hong Kong Polytechnic University, which will enable me to explore the latest developments in the theory, strategies and practice of technology industries.What attracts me most is a core set of subjects on AIBD programming and practices,which can keep abreast of innovative, up-to-date and advanced technologies and will be able to engage me in practical use. I understand that Hong Kong Polytechnic University is strong in this area, so I believe that if I am lucky enough to be admitted, I will be able to learn more senior professional knowledge and have access to more quality resources. My commitment to excellence, passion, and background could qualify me as a member of this program and will contribute to your esteemed program. Sincerely hope that I can get this opportunity. Thanks for your time and consideration.
