On a February day, Prof Jia also arrived at the foot of Mount Yuelu, except that he was not there to admire the early spring flowers, but to become a student of computer sciences in the Department of Automation at the Central South Institute of Mining and Metallurgical Engineering (the predecessor of Central South University) located at the foot of the mountain. He recalls, ‘The concept of a computer was completely alien to my family. They asked me what it was, and I said I didn’t know either. But I’ve always been a curious person, and I guess it was this sense of curiosity that drove me to choose the major.’ But interestingly for a computer major, Jia did not get a chance to see a real computer during his first year in college. At the time, computer technology was clearly not at the top of the government’s priority list. As a consequence, China lagged behind advanced countries in this area by at least ten years. Even Jia’s professors hardly knew anything about computers. They went to Beijing to see what computers looked like, attended training courses there, and compiled teaching material after returning from the trip. It was not until Jia was about to start his third year of study that the faculty introduced a DJS-131 computer, a model that was made commercially in Shanghai (DJS is simply an acronym for the Chinese words for ‘electronic computer’). That bulky machine used punched paper tape for data storage. In terms of computing power, it couldn’t even compare to today’s video game machines played by children. The first time Jia saw a desktop computer was during his postgraduate years. He was asked to purchase a desktop computer for his faculty. So he and his colleagues took a train to Guangzhou and paid close to 6,000 US dollars for an Italian brand computer. The management of the faculty feared that the precious computer might be stolen or damaged during the 24-hour train ride, so they gave Jia and his colleagues special permission to complete the return trip by airplane. ‘That was the first time I ever flew on an airplane,’ says Jia with a smile. After completing his master’s degree in 1984, Jia ତ૿࿖㬐ϓ㇓⛁ࢤᐑእˍ↽ॺ㣊⤾⏲ಾ㦦৴˗ᑘኼ♘ A keen curiosity is what has been driving Prof Jia in his exploration in computer sciences
