During senior year, Qi Yi and Yan Yan each wrote over two hundred letters to each other, totaling around four to five hundred letters.
After returning to China for four days and subtracting the time spent on the road, there was really only a weekend left, plus attending the wedding of Liu Siyan and Lu Ying. Just organizing these many letters was enough to keep Qi Yi busy.
It was no wonder that Qi Yi wasn't incessantly asking Yan Yan to meet up today, not only because he was concerned Yan Yan might get tired, but Qi Yi indeed had things to keep him busy.
"How do you code it? Can you automatically calculate the order in which the letters were written? Is it by recognizing the ink or the content?" Yan Yan expressed curiosity about Qi Yi's method of coding.
"Uh, so high-end? I've disappointed you, Xiao Qizi can only manually code.
Although we didn't write the specific date, occasionally some letters contained specific time clues, or information about the day of the week.
