美梦反映了人们美好的愿望，美梦有可能成真，那需要经过艰苦的努力；像故事里的年轻人那样，牢骚满腹，却不愿费力气改变，那就只能做个黄粱美梦，醒来落得一场空了。 Dreams reflect people's beautiful aspirations, and dreams may come true, but it requires hard work. Like the young man in the story who complains a lot but is unwilling to make an effort to change, one might end up having a fleeting dream like the "Dream of the Yellow Millet," waking up to disappointment.
