Zhangjiagang is widely regarded as the hometown of "Wu Songs," a kind of folk song sung in the local dialect in the Yangtze River Delta area.

The tradition of singing Wu Songs has been in existence for around 3,000 years.

Heyang Mountain Song was in the first batch of national intangible cultural heritage, and is taught in music classes in primary and middle schools.

Suzhou belonged to the State of Wu over 2,000 years ago, and its ancient folk songs aptly carry the same name.

Wu songs have short words and rich sentence structures. One song is always composed of four sentences. One of Wu songs says:

"Folk songs are pleasant to hear but difficult to sing;

Cherries taste good but are difficult to grow;

Rice is good to eat but difficult to plant;

Fish soup is good to drink but the fish hard to catch."

A large number of Wu songs are love songs, sung in duet by courting couples. The songs sound tender and sweet, taking the listener back to his romantic youth.
