Original text:

Qinchuan, a martial arts player, was famous in ancient times. He occasionally took a boat to watch the sunset.

All seven streams lead to the sea, and ten miles of green hills and a half enter the city.

The tomb of Qi women is deserted in autumn, and the public plays the old piano.

I have been here on this Mid-Autumn Festival night.

Translation:

Wudi Qinchuan has been famous since ancient times, and it happened to pass by by boat at night.

Seven small rivers in Changshu county flow into the big river and lead to the sea. The county wall was built on the mountain, enclosing a part of Shiliyu Mountain in the city.

In autumn, Qi Jinggong's beloved daughter's grave is covered with weeds, and it seems that Yanzi's hometown can still hear the ancient string music.

On the night of Mid-Autumn Festival, I watched the moon and recited poems on the boat.

Extended data:

Author's background: Shen Xuan, a native of Wuxian County in Ming Dynasty, used words to dive, and his works seemed to dive. Xuande was first recruited as a medical officer, and then as a medical officer. Gong is a good piano. There is also "hidden fasting".

Appreciation of works:

Changshu is nicknamed "Qinchuan". Changshu local chronicles have always had two versions. First, Changshu was nicknamed "Qinchuan" because there were rivers running north and south in ancient times, like the seven strings of the guqin. On the other hand, Changshu was nicknamed "Qinchuan" because of the "Wu Tong Garden" built by Fu Cha, the king of Wu, in Changshu during the Spring and Autumn Period.

At the end of the Spring and Autumn Period, the beloved daughter of the monarch of the State of Qi married Bo, the eldest son of He Lv, the king of Wu. Because she misses her hometown all day, she is sick because of sadness. Before she died, she asked to be buried at the top of Yushan Mountain so as to overlook the State of Qi. Yan Zi (506 BC-443 BC) was born in Changshu. The only southerner among Confucius' 3,000 disciples in the Spring and Autumn Period. Later generations called him "Yan Zi" out of respect for him.

Poets are familiar with local history and have profound cultural and historical connotations.
