Looking at the old times from Niuzhu Night Sleeping-Interpreting the word "empty" in couplets.

From "Full Moon" in Niuzhu to "Homesickness". When Xie Shang crossed the river by the moon and met Yuan, Lang Yin was in a distant place that was most likely to associate ancient and modern things. This poetic story is consistent with the place in front of the poet (Niulan Xijiang River) and the scenery he met (blue sky and bright moon). So although there is a great leap between "hope" and "memory", it feels natural and reasonable to read. The word "Wang" contains the poet's communication from now to now and the ideological activities that are not directly expounded. The word "empty" of "empty memory" is quoted below.
