The Vietnamese word "lum khum" is a term that is often used in the local dialects. It describes a posture or position where a person is slightly bent over or hunched. This can be due to age, fatigue, or simply a casual way of standing or sitting.
In some contexts, "lum khum" may also refer to a state of being disorganized or messy, reflecting a general lack of order or tidiness in a person's surroundings or personal situation.
