Heptachord Terrace, also named Boya Terrace, is located on the bank of Moon Lake, western foot of Tortoise Hill in Hanyang district.
Story goes that Yu Boya used to be a famous musician in Chu kingdom during the Spring and Autumn Period (770 - 476 B.C.). Although good at musical instrument, he was always depressed for few people can keenly comprehended his music. One day, on his way back to his country after a diplomatic mission, he was blocked here by a sudden heavy rain. When it cleared up, Yu Boya played a piece of music. Zhong Ziqi, a woodcutter, understood quite well the message conveyed in Boya's music - a vivid description of mountains and rivers, then traced the music and found Yu Boya. Thus the two became bosom friends. One year later, when Ziqi died, Boya, knowing there would be no one else to appreciate the beauty of his music, smashed his lute in grief and never again played music. Later people built this terrace in memory of the friends.
