There are different opinions about the location of Yuli County in Han Dynasty. There are records in Taiping Universe in the Northern Song Dynasty and Qi Cheng in the Yuan Dynasty: "Yuli, Han County and Houhan Province were merged into Mu Ping, so they were named Yuli because of the fertile land near the port." However, the positions recorded in the two books are different. The former is "120 miles southeast of this county (referring to Ninghai Prefecture)" and should be in Rushan City today; The latter is recorded as "eighty miles west of Ninghai House", which belongs to Fushan District of Yantai City today. Since then, the unified annals of Daming has been called "120 miles southeast of Ninghai House". "Dengzhou Zhi" says: "The harbor water is in the southwest of Ninghai Prefecture. According to its topography, the city should be in Ninghai, and today's age is its old address. Qi Cheng mistakenly refers to the southwest as the northwest ear. " In the Qing Dynasty, Qi Cheng was cited as a story in Fushan County Records: "There is an old city behind Wuligongjia Island in the northeast of the county, which the natives call Ruth, but it is suspected to be this city". At the end of Qing Dynasty, "Miscellaneous Affairs in Dengzhou" said: "Mu Ping and Li Yu are in Fushan today". In Shandong Tongzhi of the Republic of China, it was recorded that "Yuli is located in Yingzitou, northeast of Fushan City". The Records of Fushan County (1990) still records Yuli County in the north of Zhang Qi Village in Fushan District according to the old theory of the Records of Fushan County in Qing Dynasty.

1933, the compilation of Mu Ping County Records of the Republic of China was completed in Pan Qing. In order to find out the exact site of the ancient city of Yuli, we made field trips to Yuli and Beiyingzitou of Fushan respectively, visited the local elders and observed its topography. We thought that "Han County belongs to Fushan County today, so we should not just go to Wuli to set up Yuli County, and Fushan has no harbor water (now called Rushan River). There are two villages in the north of the ancient city, Yin Cheng and Yu Li. The names of the two villages should refer to the meaning behind the city, using the old county name, 120 miles away from Ninghai House (now Mu Ping County), which is exactly the same as that contained in the annals of Ming Yi. Undoubtedly it is the old address of Yuli City. " In order to prevent future generations from misinformation, the Mu Ping County Records Committee set up the "Yuli Ancient City Monument" on 1935, and wrote an inscription in Pan Qing.

The site of Han Yuli Ancient City is located on the east-west plain south of Yincheng Village in Yuli Town. The ancient city is surrounded by mountains, with Nanhe in Yincheng Village in the north and Yongjia Village in the south. 1950, several Han tombs were found on the south and north hills of the ancient city ruins. The North Yongjia Han population is about 1000 meters long from north to south and about1000 meters wide from east to west. There are three big tombs on the north hill of Yincheng Village, two of which were destroyed in the 1970s, and now there are 1 tombs. Since the 1960' s, local people have excavated many ancient tombs and nearly 100 cultural relics, such as stone reliefs, sheep, pottery, wooden figurines, bronze mirrors, bronze swords, gilded geese, etc., and found many building materials such as bricks, tiles, supports and pillars of the Han Dynasty. During the period of 1987, when the villagers in Yin Cheng village dug a big well, they found that there was muddy soil under the cultivated soil, which was about 2.5 meters thick, and there was peat soil under the muddy soil, including bricks, tiles, pillars and pottery pots. From the analysis of underground silt, the ancient city may be submerged by floods and silt at some time.

Although the ancient city has disappeared, the place names still exist. According to the research of Rushan Geographical Names Office, the name of Yuli Village originated from the ancient name of Yuli County, and was later renamed Yuli because the word "plow" was too vulgar. The name of Yincheng Village means the north of the city. Both villages are located by the water of the harbor. The formation of place names is not accidental coincidence, but people's records of history for thousands of years. The ancient city of Yuli is undoubtedly in today's Yuli Town, Rushan City.
