The origin of Yancheng's name is as follows:

In the early Qin Dynasty, people began to take boiled salt from Yancheng. At that time, the mouth of Huaihe River was in the north of Yancheng, and Yancheng had no city name. Later, the more salt was cooked, the more people knew about it, and people could not live without it. Therefore, the circulation of salt became wider and wider, and the profit of salt became bigger and bigger. "Boiled salt is as much as a city wall!"

Because it is near the Huaihe River, the boiled salt is called "Huai salt".

Because of the salt production, many people from around were attracted to immigrate to Yancheng to cook salt, and the imperial court also planned to migrate some people to Yancheng to cook salt. Salt has also become the main official tax of the court, and it has become a commodity that the court specializes in. The influence of salt is getting bigger and bigger. By the Western Han Dynasty, the tax revenue of salt has reached 1/3-2/3 of the national fiscal revenue. As a city, Yancheng has begun to take shape. Emperor Wu of the Han Dynasty established "Yandu" county in the name of salt.

in the eastern Jin dynasty, the emperor personally named the city named after salt "Yancheng". The name has survived to this day.

Yancheng Folk Custom:

In the rural areas around Yancheng and Funing, there was a witch-hunting activity in history, which included: praying for a bumper harvest to hold a green seedling meeting and a seedling-adding meeting; Extend happiness and eliminate disasters, and be a Taiping meeting, a Mars meeting, etc. With the change of history, this kind of performance has been enriched, and after a long period of evolution, it has gradually developed into a incense play.

Incense Opera is a kind of local drama closely related to the folk belief in ghosts and gods, also known as Sanhuozi and Sankezi, which was finally formed around the first year of Tongzhi in Qing Dynasty (1862). Its singing is composed of Xiang Huo Diao, which is popular in China, and Huai Bengzi, which is popular in Huaiyin and Baoying. At the same time, incense performers often join hands with door-playing artists, so many tunes in incense dramas come from door-playing.
