Since in middle school, I have been told that China covered a vast amount of areas, which are rich in natural resource including various minerals and ores. But in contrast China always has to import a huge amount of advanced metal materials produced in other countries at very high prices. This dilemma China has faced prompted me to ask why China can not produce high quality metal materials as other countries do. To explore the answer, I am determined to pursue a general study on how the metals are produced. Following my passion, in 2005, majoring in Metallurgical Engineering, I entered the School of Metallurgical Science and Engineering of Central South University, the best Department of one of China's most prestigious universities. Seven years have passed and I have since earned a Master degree from college.
