After my elementary and junior high school education at my hometown, I went on my senior high school education at a public vocational technical high school at the neighboring county Fangshan. Courses I have taken there include: mechanical structure, applied² mechanical dynamics³, material strength, heat treatment analysis, and electrical engineering. I also had practice courses on lathe⁴ work, bench work, casting, engineering drawing, and electronic television repair skill. After graduation from this technical school, I found a job at the Evergreen⁵ Traffic Corp. When I had worked one year in mechanical design and heat treatment analysis, I was admitted to the Computer Science Department of Beijing Institute of Technologies.

　　Computer science education was an extension of my pursuit in electronic knowledge, it had led me into the world of applied electronics. Courses I had taken are: Calculus⁶, Computer Programming (FORTRAN, COBOL, ASSEMBLY, and BASIC), Computer architecture, algorithm, maintenance, system analysis, and some related courses in Accounting⁷, Statistics, Operating research, Digital value analysis.

　　Beginning at the second year of college, I participated in a work study program and was assigned to the computer center of Far East Textile Corp. as night-shift computer operator, The computers I dealt with were CDC 3300 MSOS and IBM 370-115 DOS/VS system. The major work I had done was the system transference of CDC 3300: MSOS to IBM 370-115 DOS/VS.

　　In 1989, I was employed by China Automobile⁸ Corp. as a computer programmer, and was informed to work on the first of June.

　　For the first six months of my service, I was in charge of the IBM 4331; DOS/ VSE System Operation, and later on dealt with personnel / payroll⁹ and financing system programming works. In the second year, I was promoted to be a system analyst¹⁰ for personnel/ payroll system. In an attempt to upgrade the efficiency of computer data process and to simplify users operating procedures, I redesigned the whole working system and I successfully transferred a Batch¹¹ operation from oriented system to on-line system. In the third year, I spent five months in the developing of subsystem of financing-accounting. No sooner had I finished that system than I was reassigned as a Subsystem Programmer in charge of DOS / VSE, CICS, and VTAM. At that position I have full responsibility for affairs of technical transition, system development, recruit training, and network communications.

　　With the elapse of time and the accumulation of experiences, I am now familiar with all of the popular computer languages: FORTRAN, COBOL, ASSEMBLY, and BASIC. Other than these languages, I have also learned and practiced in planning, designing, and analyzing¹² of the following computer applications: DL/ 1, Data Base, On-line (CICS, BMS), Data Communication Network (ACF/ VTAM / NCP), VM, DOS / VSE Operating System: Personnel / Payroll, Accounting Application System and etc.. For these achievements I owe a great deal to China Information Association Since I have taken almost every training course they have offered.

　　With the ever-increasing level of my work, I am feeling strongly that the theoretical study and actual practice are equally important and dependent on each other. Though I personally possess many years of experiences in actual practices, there is always need for me to extend my existing theoretical basis for future research. My love for computer sciences and my inquisitiveness¹³ had pushed me to apply for your graduate school admission, and I have decided¹⁴ . should I be accepted by you, I will concentrate on the field of net-work-data-communication, then make a breakthrough on my current ways of thinking in computer related research and development. Finally, I expect that I, myself, as one member of today's world of computer domain¹⁵, I should strive to offer my best professional computer service to our society.
