Xiao is a Chinese character, and its common usage is a verb, which means to know and understand. Its pronunciation is Xi m: o, and its glyph consists of day and month, which is very interesting. In addition, Xiao also has the meaning of a noun, which refers to the time just before dawn, such as seeing the morning light in the fog, which can be said to be morning light in the fog.

Both dawn and morning indicate the time of the morning, and there is also a description in Zhuangzi's Inner Chapter: A Happy Journey that "the dawn will break, otherwise a corner will be exposed and disappear among the waves". The difference is that Xiao pays more attention to the stage of dawn, while morning refers to a period of time in the morning. Dawn and morning are also different in context. For example, in poetry, dawn is often used to describe the beauty of dawn, while dawn is often used to describe the activities of getting up early and dawn.

Both "small" and "bright" mean "bright", but there are still differences in semantics. Xiao pays more attention to the process from darkness to light. For example, in the long night, when the sky is getting brighter, it is called Xiao. Ming pays more attention to the transparency and clarity of light. For example, looking at clear water can be said to be clear and clean. Generally speaking, dawn is a point in time and dawn is a state.
