First of all, Nalan Xingde, named Rong Ruo, was from the Qing Dynasty. He did write a poem about Qiu Si, but the name of the poem is Sauvignon Blanc, which means "one mountain, one journey, one water journey, one night, a thousand lights on the other side of Guan Yu". The wind is snowier and homesickness is broken. There is no such sound in my hometown.

Secondly, Wang Jian, a native of the Tang Dynasty, wrote many Yuefu poems, and Wang Jian was only known as Zhang Wang Yuefu with Zhang Ji of the Tang Dynasty.

Finally, Zhang Ji wrote a homesick poem called Qiu Si. In Luoyang city, seeing the autumn wind, the writer's book is full of worries and endless words.

So you should have mistaken the author of Qiu Si from the beginning, not Nalan, but Zhang Ji. Zhang Ji's name is Wenchang, which is often called "Zhang Shui Department". His Yuefu poems are as famous as Wang Jian's Yuefu poems, and are called "Zhang Wang Yuefu".
