Half a Step

In 2021, a middle-aged man who has been in business for half his life opens his eyes and returns to 1992. He is still the top student in the economics department! When I graduated, my teacher slapped the table: "I'll help you join the system for your files, it's safe!" He frowned: "Teacher, I am from the Department of Economics. Do you want me to join the system?" The teacher waved his hand: "Listen to me, you are not suitable for business! Joining the system can better utilize your strengths and benefit the people!" Looking at the locked files, he chuckled with nearly 30 years of advanced memory: I am familiar with business, how about the system? Then I'll try another track!
