Wen Chaoshen was almost completely certain of this point, because the Qi Kingdom was different from the other three kingdoms. Even a refugee like Wen Chaoshen from outside the county knew that the first thing for those who entered the Qi Kingdom's military was not to go to the battlefield. New recruits sent to the border, even if they didn't encounter battles, would only serve as cannon fodder against bandits and nomads, with less than one in ten surviving.

The first thing these selected new soldiers did was receive basic education. The Langan Pavilion would send scholars to teach them the simplest Thousand Character Classic, for future military needs and daily use.

Therefore, any soldier who served in the Qi Kingdom for more than a year would be literate and able to write.

If they really needed to write to their families, there was no need to find someone to write for them. That's why Wen Chaoshen was so sure that the letter Mi Fang had received was not written by her son, Zhang Changgong.
