This is a well-received poem. The beauty of the whole poem lies in taking two beautiful pictures of nature and combining them. One is the gorgeous scene of the sunset reflected on the river, and the other is the hazy night when the crescent moon rises and the dew is crystal clear. Both of them have their own beautiful scenery, and it is even more exciting to watch them together. Poets also add metaphors to their poems appropriately to make the scenery more vivid.
The first two sentences of Ode to Mujiang were written before sunset (for a short time) or at sunset; The last two sentences are mainly written after sunset (short time), that is, dusk; The last two sentences also lead to a period of time in the evening. This is completely in line with the author's viewing order, that is, the author saw the sunset before sunset, the moon like a bow after sunset, and the dew like a real pearl at night. Most materials think that "the moon is like a bow" and "the dew is like a pearl" are seen by the author at the same time at night, writing in the sky before and writing underground after. In fact, this is because of the lack of common sense of astronomy and meteorology, ignoring the "time difference" between two natural phenomena. As mentioned above, the author can only see "the third day of September" and "the moon is like a bow" shortly after sunset. At this time, because the sun has just set, the heat lost on the ground is not much, and the cool dew has not yet formed; By the time the night is "like a real pearl", the moon like a bow has sunk below the western horizon.
