Some soldiers are forbidden to gamble in the army, but they can secretly play gambling games in their accounts.
But in some armies, it is so strict in order to sympathize with the hardships and loneliness of soldiers. At this time, there were many ways of entertainment for soldiers, but gambling and drinking were the main ways.
China has formed a wine culture in ancient times, especially the wine brewed in ancient times, which is particularly fragrant and less intoxicating. Therefore, every army will bring a lot of wine when marching and fighting, either when soldiers are bored or when soldiers train on the eve of the war.
Not to mention gambling, China people like gambling because of their ancestors. It would be strange if there were no soldiers in any army gambling to kill time.
