Recently there was a competition for Tsinghua civil engineering majors. Whose structure can support the most weight? And so on. At the end of the competition, a professor handed out prizes to the winners. After the awards ceremony, the professor who had handed out the awards said to a colleague, “I don’t like this job.” His colleague was surprised: What was so bad about handing out awards? The professor explained that the students’ names sometimes included characters so obscure that he didn’t know them. Which was embarrassing.
