That is, Meng Guan didn't truly share with He Song everything they experienced on the battlefield in order to keep him from worrying about the safety of Meng Guan and Wei Fan.
It was like children traveling far from home usually only sharing good news and concealing their worries when communicating with their families.
For the sake of not worrying He Song, Meng Guan also chose to selectively hide some things from him.
For example, He Song didn't see anything in Meng Guan's letter about their recent encounter when they were surrounded and fought two enemies on their own.
Not to mention this.
Even when talking about the dangerous moments Meng Guan and Wei Fan experienced together in the past, Meng Guan always downplayed them.
Take, for example, their experience at the Bamboo Mountain Immortal Pavilion and Meng Guan's previous communications with He Song. The descriptions of battles he heard from Meng Guan were more or less the same.
