How can I meet a soldier brother in reality?

I don't think it's easy, because I haven't met Brother Bing except for military training. Brother bing trains in the army every day and doesn't come out very often. Only when they are on vacation will they go home. However, at that time, most of them were wearing ordinary clothes, which was difficult to recognize. Some of them are still wearing clothes issued by the army. If you are close to the army, you can go out for a walk during lunch break and see if you can meet them.
