Did a soldier sign a confidentiality agreement in the army? When my brother came back as a soldier, his family asked him how he was doing in the army, and he said yes.
As a soldier, confidentiality agreement is the first, and there is always a string. This is also the principle of China soldiers. We should protect the country's military secrets as soon as possible, because we don't know who might be spies and traitors. And everyone likes to talk about things that others don't know when chatting at parties, so no matter what kind of family and relatives, they will keep their mouths shut and don't talk.
