Version 1: This is an earlier version. Brother Dong said that he taught himself programming in his spare time at night, but he didn't have a computer, so he drew a keyboard on the bed board and knocked on the textbook to learn. This version boasts too much, which is obviously too fake.
Version 2: This is a later improved version. It is said that this version was also learned at night. He didn't have a computer, so he borrowed one from his relatives, but this computer can only be used by him at night. He taught himself programming in the dormitory with this computer that can only be used at night. This version is relatively credible, but it is also very fake. At that time, computers were rare goods, each of which was about 20,000 RMB (the monthly income at that time was generally 300-500 yuan), and most of them were purchased by the government, so the people who bought private computers were not ordinary people. Brother Dong only sewed 500 pieces in his crotch when he was at school. How can a rich relative borrow a computer as soon as he makes a move? In addition, computers can't be used during the day, but only at night, which is very suspicious. At that time, computers were all desktops, big and heavy. If Dong Ge's dormitory has a computer, why can't it be used during the day? Do his relatives come here every day, move out during the day and move back at night? Valuables come and go every day. Is that really the case?
