There are different opinions on how Yuyao got its name. One theory is that "Fengtu Ji" records that the land sealed by Shun's concubine, Shun's surname was Yao, so it was called Yuyao ("The land sealed by Shun's concubine, Shun's surname was Yao, so it was Yuyao"). Another saying is that according to "Yue Jueshu", Xia Shaokang was granted less than no Yu Yu in Kuaiji to commemorate Yu, and Yao was his county, so it was called Yuyao. " Shanhaijing " Guo Pu notes that Juyu Mountain is in the south of Yuyao County in Kuaiji and in the north of Juzhang County, so the two counties are named after this. This is the third theory. There is another saying, "There is Juyu Mountain in the city, and there is and Yaojiang in the south", hence the name. Another theory is that the "Explanation of Names of Counties and Counties" of the Ming Dynasty said that the county was under the jurisdiction of Kuaiji, west of Yuyao Mountain, and there was a surname of Yao in the east of the river, so it was called Yuyao. Recently, some people have argued that Yuyao is a place name in Yue language, and its meaning is Shi Ming. Yuyao County was established in the Qin Dynasty (some say it was built by the Han Dynasty), and it belongs to Kuaiji County. The county seat was built in the fifth year of Jian'an Period (200 AD) of the Eastern Han Dynasty and is one of the ancient counties in eastern Zhejiang Province. According to " Taiping Huanyu Ji ": In the early Tang Dynasty, "the territory of Yuyao encompasses Mingzhou in the east and Shangyu in the west. It is a giant town in Yuezhou". It was once promoted to Yaozhou (Yaozhou was established in the fourth year of Wude in Tang Dynasty (621 AD) ). In the Song Dynasty, it was called "Wang County", "the most famous town in the southeast". In the first year of Yuanzhen (1295), it was changed to Yuyaozhou . In the second year of Hongwu in the Ming Dynasty (1369), the prefecture was abolished and the county was restored. On November 8, 1911 (September 18, the third year of Xuantong in the Qing Dynasty), Yuyao was "recovered".
Yuyao was liberated on May 23, 1949. After the founding of New China, the territory changed many times. The biggest one was in 1954. The cotton area north of Dagutang was placed under Cixi County, and the rice area and mountainous area in the west of Cixi County were placed under Yuyao County. On July 26, 1985, the county was removed and a city was established, with 9 districts, 8 towns, and 63 townships. Affiliated to Ningbo City hosting.
